Go Strings — Rules and Patterns
1. Runes, bytes, and len
- A Go
stringis an immutable sequence of bytes, not runes. len(s)returns the byte count, not the character/rune count.- A
runeis an alias forint32and represents a single Unicode code point. - Under UTF-8 a code point may occupy 1-4 bytes.
- To count runes, use
utf8.RuneCountInString(s).
s := "cafe\u0301" // "cafe" + combining accent = 5 runes, but check byte length
fmt.Println(len(s)) // byte count (likely 6)
fmt.Println(utf8.RuneCountInString(s)) // rune count (5)
2. String iteration
Prefer the range value variable for rune access
When ranging over a string, the index i is the byte offset of the rune, and the value r is the rune itself. Accessing s[i] gives a single byte, not the rune.
Wrong:
for i := range s {
fmt.Printf("%c", s[i]) // prints individual bytes, corrupts multi-byte runes
}
Correct — iterate over runes:
for i, r := range s {
fmt.Printf("position %d: %c\n", i, r) // i = byte offset, r = full rune
}
Accessing the i-th rune
If you need the rune at a logical index (not byte offset), convert to []rune first:
r := []rune(s)[4]
This allocates a new slice (O(n)), so avoid it in hot loops. If the string is known to
be pure ASCII, rune(s[i]) is safe and allocation-free.
3. Trim functions — TrimRight/TrimLeft vs. TrimSuffix/TrimPrefix
These are commonly confused. The semantics are fundamentally different:
| Function | Behaviour |
|---|---|
strings.TrimRight(s, cutset) | Removes all trailing runes that appear anywhere in cutset, one by one, until a rune not in the set is found. |
strings.TrimSuffix(s, suffix) | Removes the exact trailing suffix substring once. |
strings.TrimLeft(s, cutset) | Same as TrimRight but from the left. |
strings.TrimPrefix(s, prefix) | Same as TrimSuffix but from the left. |
strings.Trim(s, cutset) | Applies both TrimLeft and TrimRight. |
strings.TrimRight("123oxo", "xo") // "123" (strips o, x, o individually)
strings.TrimSuffix("123oxo", "xo") // "123o" (strips the suffix "xo" once)
Rule: When you want to remove a known fixed string from the start/end, use
TrimPrefix / TrimSuffix. When you want to strip a set of characters, use
TrimLeft / TrimRight / Trim.
4. String concatenation
Avoid += in loops
Strings are immutable. Every += allocates a new string and copies all previous
bytes. This is O(n^2) for n concatenations.
Wrong:
func concat(values []string) string {
s := ""
for _, v := range values {
s += v // new allocation every iteration
}
return s
}
Use strings.Builder in loops
func concat(values []string) string {
var sb strings.Builder
for _, v := range values {
sb.WriteString(v)
}
return sb.String()
}
Pre-grow the builder when total size is known or estimable
Computing the total byte length first and calling Grow avoids internal slice
re-allocations. Benchmarks show ~78% speedup over a non-pre-allocated Builder.
func concat(values []string) string {
total := 0
for _, v := range values {
total += len(v)
}
var sb strings.Builder
sb.Grow(total)
for _, v := range values {
sb.WriteString(v)
}
return sb.String()
}
When += is fine
For a small, fixed number of concatenations (roughly <= 5) or one-off formatting,
+=, fmt.Sprintf, or + are acceptable and more readable.
Safety note
strings.Builder is not safe for concurrent use.
5. Avoid useless string <-> []byte conversions
Each conversion between string and []byte allocates and copies because strings
are immutable.
Rule: If input arrives as []byte (from io.Reader, io.ReadAll, etc.) and the
result is also []byte, keep the entire pipeline in []byte. The bytes package
mirrors almost every function in strings:
strings function | bytes equivalent |
|---|---|
strings.TrimSpace | bytes.TrimSpace |
strings.Split | bytes.Split |
strings.Contains | bytes.Contains |
strings.Index | bytes.Index |
strings.Count | bytes.Count |
Wrong — double conversion:
func getBytes(reader io.Reader) ([]byte, error) {
b, err := io.ReadAll(reader)
if err != nil {
return nil, err
}
return []byte(strings.TrimSpace(string(b))), nil // 2 extra allocs
}
Correct — stay in []byte:
func getBytes(reader io.Reader) ([]byte, error) {
b, err := io.ReadAll(reader)
if err != nil {
return nil, err
}
return bytes.TrimSpace(b), nil // zero extra allocs
}
Guideline: Before reaching for the strings package, check whether the whole
workflow can use bytes instead.
6. Substrings and memory leaks
Substring expressions like s[a:b] produce a string that shares the same backing
array as the original. If the original string is large (e.g., a log line of thousands
of bytes) and you store only a small substring, the entire original backing array
stays in memory and cannot be garbage-collected.
Leaky:
uuid := log[:36] // uuid's backing array still holds the full log string
s.store(uuid)
Fix: copy the substring
Go >= 1.18 — use strings.Clone:
uuid := strings.Clone(log[:36]) // fresh 36-byte allocation
Pre-1.18 — manual deep copy:
uuid := string([]byte(log[:36])) // forces a new backing array
Note: some linters flag string([]byte(...)) as a "redundant conversion" — this
warning is incorrect in this context because the round-trip deliberately breaks
backing-array sharing.
Substring indexing caveat
s[a:b] operates on byte indices, not rune indices. For multi-byte runes,
convert to []rune first:
s := "Hêllo, World!"
sub := string([]rune(s)[:5]) // "Hêllo" — rune-safe
Quick-reference checklist
-
len(s)used only when byte count is intended;utf8.RuneCountInStringfor rune count. - String range loops use the value variable (
r), nots[i], for rune access. -
TrimRight/TrimLeftnot confused withTrimSuffix/TrimPrefix. - No
+=concatenation inside loops;strings.BuilderwithGrowpreferred. - No unnecessary
string<->[]byteround-trips;bytespackage used when possible. - Substrings of large strings copied via
strings.Clone(orstring([]byte(...))) before long-term storage.

# Go Strings — Rules and Patterns
## 1. Runes, bytes, and `len`
- A Go `string` is an immutable sequence of **bytes**, not runes.
- `len(s)` returns the **byte count**, not the character/rune count.
- A `rune` is an alias for `int32` and represents a single Unicode code point.
- Under UTF-8 a code point may occupy 1-4 bytes.
- To count runes, use `utf8.RuneCountInString(s)`.
```go
s := "cafe\u0301" // "cafe" + combining accent = 5 runes, but check byte length
fmt.Println(len(s)) // byte count (likely 6)
fmt.Println(utf8.RuneCountInString(s)) // rune count (5)
```
## 2. String iteration
### Prefer the range value variable for rune access
When ranging over a string, the index `i` is the **byte offset** of the rune, and the value `r` is the **rune itself**. Accessing `s[i]` gives a single byte, not the rune.
**Wrong:**
```go
for i := range s {
fmt.Printf("%c", s[i]) // prints individual bytes, corrupts multi-byte runes
}
```
**Correct — iterate over runes:**
```go
for i, r := range s {
fmt.Printf("position %d: %c\n", i, r) // i = byte offset, r = full rune
}
```
### Accessing the i-th rune
If you need the rune at a logical index (not byte offset), convert to `[]rune` first:
```go
r := []rune(s)[4]
```
This allocates a new slice (O(n)), so avoid it in hot loops. If the string is known to
be pure ASCII, `rune(s[i])` is safe and allocation-free.
## 3. Trim functions — `TrimRight`/`TrimLeft` vs. `TrimSuffix`/`TrimPrefix`
These are commonly confused. The semantics are fundamentally different:
| Function | Behaviour |
|---|---|
| `strings.TrimRight(s, cutset)` | Removes **all trailing runes** that appear anywhere in `cutset`, one by one, until a rune not in the set is found. |
| `strings.TrimSuffix(s, suffix)` | Removes the exact trailing `suffix` substring **once**. |
| `strings.TrimLeft(s, cutset)` | Same as TrimRight but from the left. |
| `strings.TrimPrefix(s, prefix)` | Same as TrimSuffix but from the left. |
| `strings.Trim(s, cutset)` | Applies both `TrimLeft` and `TrimRight`. |
```go
strings.TrimRight("123oxo", "xo") // "123" (strips o, x, o individually)
strings.TrimSuffix("123oxo", "xo") // "123o" (strips the suffix "xo" once)
```
**Rule:** When you want to remove a known fixed string from the start/end, use
`TrimPrefix` / `TrimSuffix`. When you want to strip a *set of characters*, use
`TrimLeft` / `TrimRight` / `Trim`.
## 4. String concatenation
### Avoid `+=` in loops
Strings are immutable. Every `+=` allocates a new string and copies all previous
bytes. This is O(n^2) for n concatenations.
**Wrong:**
```go
func concat(values []string) string {
s := ""
for _, v := range values {
s += v // new allocation every iteration
}
return s
}
```
### Use `strings.Builder` in loops
```go
func concat(values []string) string {
var sb strings.Builder
for _, v := range values {
sb.WriteString(v)
}
return sb.String()
}
```
### Pre-grow the builder when total size is known or estimable
Computing the total byte length first and calling `Grow` avoids internal slice
re-allocations. Benchmarks show ~78% speedup over a non-pre-allocated Builder.
```go
func concat(values []string) string {
total := 0
for _, v := range values {
total += len(v)
}
var sb strings.Builder
sb.Grow(total)
for _, v := range values {
sb.WriteString(v)
}
return sb.String()
}
```
### When `+=` is fine
For a small, fixed number of concatenations (roughly <= 5) or one-off formatting,
`+=`, `fmt.Sprintf`, or `+` are acceptable and more readable.
### Safety note
`strings.Builder` is **not** safe for concurrent use.
## 5. Avoid useless `string` <-> `[]byte` conversions
Each conversion between `string` and `[]byte` allocates and copies because strings
are immutable.
**Rule:** If input arrives as `[]byte` (from `io.Reader`, `io.ReadAll`, etc.) and the
result is also `[]byte`, keep the entire pipeline in `[]byte`. The `bytes` package
mirrors almost every function in `strings`:
| `strings` function | `bytes` equivalent |
|---|---|
| `strings.TrimSpace` | `bytes.TrimSpace` |
| `strings.Split` | `bytes.Split` |
| `strings.Contains` | `bytes.Contains` |
| `strings.Index` | `bytes.Index` |
| `strings.Count` | `bytes.Count` |
**Wrong — double conversion:**
```go
func getBytes(reader io.Reader) ([]byte, error) {
b, err := io.ReadAll(reader)
if err != nil {
return nil, err
}
return []byte(strings.TrimSpace(string(b))), nil // 2 extra allocs
}
```
**Correct — stay in `[]byte`:**
```go
func getBytes(reader io.Reader) ([]byte, error) {
b, err := io.ReadAll(reader)
if err != nil {
return nil, err
}
return bytes.TrimSpace(b), nil // zero extra allocs
}
```
**Guideline:** Before reaching for the `strings` package, check whether the whole
workflow can use `bytes` instead.
## 6. Substrings and memory leaks
Substring expressions like `s[a:b]` produce a string that **shares the same backing
array** as the original. If the original string is large (e.g., a log line of thousands
of bytes) and you store only a small substring, the entire original backing array
stays in memory and cannot be garbage-collected.
**Leaky:**
```go
uuid := log[:36] // uuid's backing array still holds the full log string
s.store(uuid)
```
### Fix: copy the substring
**Go >= 1.18 — use `strings.Clone`:**
```go
uuid := strings.Clone(log[:36]) // fresh 36-byte allocation
```
**Pre-1.18 — manual deep copy:**
```go
uuid := string([]byte(log[:36])) // forces a new backing array
```
Note: some linters flag `string([]byte(...))` as a "redundant conversion" — this
warning is incorrect in this context because the round-trip deliberately breaks
backing-array sharing.
### Substring indexing caveat
`s[a:b]` operates on **byte** indices, not rune indices. For multi-byte runes,
convert to `[]rune` first:
```go
s := "Hêllo, World!"
sub := string([]rune(s)[:5]) // "Hêllo" — rune-safe
```
