For the Span-of-byte (Span-first) equivalents and the low-level buffer/pool machinery, see the bundled reference files.\n---\n\n# Slice, SliceReader, SliceWriter & friends\n\n`Slice` is the workhorse for binary data in this codebase. It is a **`readonly struct`** (in namespace `System`) that wraps a segment of a `byte[]` — its three fields are `Array` (the backing array, possibly null), `Offset`, and `Count`. It predates `Span<T>` and is the logical equivalent of **`ReadOnlyMemory<byte>`**, but with a large library of helpers for turning bytes into and out of real-world types. Keys and values in the FoundationDB binding are `Slice`s.\n\n> **Two things to internalize first:** (1) a `Slice` is a **view**, not a copy — it shares the backing array. (2) `Slice.Nil` (no array) and `Slice.Empty` (zero-length array) are **different** and the distinction is load-bearing. Both are covered below.\n\nFor the Span-first equivalents (`SpanReader`/`SpanWriter`, `ISpanEncodable`) read [`references/span-readers-writers.md`](references/span-readers-writers.md); for pooled buffer-building (`ISliceBufferWriter`, `SlicePool`, `ValueBuffer<T>`, allocators) read [`references/buffers-and-pooling.md`](references/buffers-and-pooling.md).\n\n## 1. Nil vs Empty — the #1 gotcha\n\n| | `Slice.Nil` | `Slice.Empty` |\n|---|---|---|\n| backing array | none (null-like) | a zero-length array |\n| `IsNull` | `true` | `false` |\n| `IsEmpty` | `false` | `true` |\n| `IsNullOrEmpty` | `true` | `true` |\n| `IsPresent` | `false` | `true` |\n| `GetBytes()` | returns **`null`** | returns an **empty array** |\n| `ToStringUtf8()` | returns **`null`** | returns **`\"\"`** |\n| `==` | `Nil != Empty` | distinct |\n| `CompareTo` | `Nil` and `Empty` compare **equal** (both sort first) |\n\n`tr.GetAsync(key)` returns **`Slice.Nil`** for a missing key, so the canonical \"does it exist?\" check is `value.IsNull` (or `IsNullOrEmpty` if an empty value also counts as absent). Use `Nil` to mean *absent* and `Empty` to mean *present but zero-length*.\n\n```csharp\nvar v = await tr.GetAsync(key);\nif (v.IsNull) { /* key does not exist */ }\n```\n\n## 2. Slice is a view — copy when you must own it\n\nConstructing a `Slice` from a `byte[]` does **not** copy; the `Slice` references the array, so mutations to the array are visible through the slice (and its `.Span`). When you need an independent owner, copy:\n\n```csharp\nbyte[] buf = ...;\nvar view = buf.AsSlice();        // shares buf — buf[i] = x is visible through view\nbyte[] mine = view.ToArray();    // defensive copy\nbuf[0] = 0xFF;                   // changes `view`, not `mine`\n```\n\n## 3. Constructing a Slice\n\n```csharp\n// from arrays / spans\nbyte[] b = ...;\nb.AsSlice();                 b.AsSlice(offset, count);\nnew ArraySegment<byte>(b, o, n).AsSlice();\nSlice.FromBytes(\"abc\"u8);    // copies a ReadOnlySpan<byte>\n\n// from text\nSlice.FromStringUtf8(\"héllo\");   Slice.FromString(\"héllo\");   // UTF-8\nSlice.FromStringAscii(\"ABC\");    // ASCII only — lossy/throws on chars > 0x7F\n\n// well-known\nSlice.Empty;   Slice.Nil;   Slice.Zero(16);   // 16 zero bytes\n\n// guids / uuids / hex\nSlice.FromGuid(g);   Slice.FromUuid128(u);   Slice.FromHexString(\"00ff1234\");\n```\n\n### Three integer encodings — pick deliberately\n\nThis is a classic source of bugs. They are **not** interchangeable:\n\n| Factory | Encoding | Size (int32) | Read back with |\n|---|---|---|---|\n| `Slice.FromInt32(v)` | minimal little-endian (leading zero bytes dropped) | 1–4 bytes | `slice.ToInt32()` |\n| `Slice.FromFixed32(v)` | fixed little-endian | always 4 bytes | `slice.ToInt32()` |\n| `Slice.FromVarint32(v)` | 7-bit LEB128 varint | 1–5 bytes | (via `SliceReader.ReadVarInt32`) |\n\nEvery variant has a **big-endian** twin (`FromInt32BE`, `FromFixed32BE`, …) and 16/24/64/128-bit widths, plus floats (`FromSingle`/`FromDouble`) and `FromDecimal`. Big-endian fixed encodings are what you want when a number must **sort** correctly as a key. The minimal `FromInt32` is for standalone values you read whole with `ToInt32()` — it is *not* self-delimiting, so don't use it mid-stream (in a `SliceWriter`, use the fixed-width `WriteInt32`/`WriteInt64` or `WriteVarInt*` there; see §6).\n\n> ⚠️ **Naming differs between `Slice` and the writer/reader.** On `Slice` (standalone), `FromFixed32` = 4 bytes and `FromInt32` = minimal. On `SliceWriter`/`SliceReader` (streams), the fixed-width method is plain **`WriteInt32`/`ReadInt32`** (4 bytes LE; `*BE` for big-endian), and the varint is **`WriteVarInt32`/`ReadVarInt32`**. (`WriteFixed32`/`ReadFixed32` exist but are `[Obsolete]` — use `WriteInt32`/`ReadInt32`.)\n\n## 4. Reading values back\n\n```csharp\nslice.ToInt64();   slice.ToInt32BE();   slice.ToGuid();   slice.ToUuid128();\nslice.ToStringUtf8();    // Nil -> null, Empty -> \"\"\nslice.ToArray();         // defensive copy to byte[]\nslice.ToHexString();\n\n// zero-copy access to the bytes\nReadOnlySpan<byte> span = slice.Span;\nReadOnlyMemory<byte> mem = slice.Memory;\n\n// slicing (negative indices count from the end)\nslice.Substring(7, 6);   slice[2..5];   slice[^1..];\n```\n\n## 5. Comparison & equality\n\n`Slice` compares **lexicographically by raw bytes** (the same order FoundationDB sorts keys), is offset/array-independent (equal content compares equal regardless of backing array or offset), and supports `==`, `<`, `>`, `CompareTo`, `StartsWith`, `EndsWith`, `IndexOf`. For dictionaries/sorted sets, use `Slice.Comparer.Default` (an `IComparer<Slice>` + `IEqualityComparer<Slice>`).\n\n```csharp\na.CompareTo(b) < 0;            // a sorts before b\nkey.StartsWith(prefix);        // prefix match\nvar set = new SortedSet<Slice>(Slice.Comparer.Default);\n```\n\n## 6. SliceWriter — build a buffer\n\n`SliceWriter` is a **mutable, growable** builder (`struct`, `IBufferWriter<byte>`, `IDisposable`). Start from `default(SliceWriter)` (heap-backed, grows as needed) or `new SliceWriter(pool)` (rents from an `ArrayPool<byte>`):\n\n```csharp\nvar w = new SliceWriter();\nw.WriteInt32(42);                    // fixed 4 bytes LE  (self-delimiting)\nw.WriteVarInt32(1000);               // LEB128            (self-delimiting)\nw.WriteVarString(\"hello\");           // length-prefixed UTF-8\nw.WriteStringUtf8(\"raw\");            // raw UTF-8, NO length prefix\nw.WriteBytes(payload);               // append bytes\nSlice result = w.ToSlice();          // the written region (a view into the writer's buffer)\n```\n\n- Use **self-delimiting** writes (fixed-width `WriteInt32`/`WriteInt64`/…, `WriteVarInt*`, `WriteVarString`) for anything you'll parse back sequentially. A raw `WriteStringUtf8`/`WriteBytes` has no length, so the reader must already know the length.\n- `Position`, `Reset()`, `Rewind()`, `Skip(n)`, `Allocate(n)`/`AllocateSpan(n)` (reserve space to fill in place).\n- **Pooling caveat:** if you pass an `ArrayPool<byte>`, you must either `Dispose()` the writer or hand the buffer off with `ToSliceOwner()` — otherwise the rented array is never returned. `ToSlice()` returns a *view into the writer's buffer*; if the writer (or its pooled buffer) is disposed/reused, that view becomes invalid — `ToArray()` or `ToSliceOwner()` it to keep it.\n\n## 7. SliceReader — parse a buffer\n\n`SliceReader` is a **forward cursor** over a `Slice`. Pair each read with the matching write:\n\n```csharp\nvar r = result.ToSliceReader();\nint n     = r.ReadInt32();           // <-> WriteInt32  (fixed 4 bytes)\nuint k    = r.ReadVarInt32();        // <-> WriteVarInt32\nstring s  = r.ReadVarString();       // <-> WriteVarString\n// raw / fixed-length string written without a prefix: read the known number of bytes\nstring raw = r.ReadBytes(3).ToStringUtf8();\nSlice rest = r.ReadToEnd();\n```\n\n`Remaining`, `HasMore`, `Head` (bytes already read), `Tail` (bytes not yet read), and non-advancing `PeekByte()`/`PeekBytes(n)` round out the API. There is **no** `ReadStringUtf8(n)` — use `ReadBytes(n).ToStringUtf8()`.\n\n## 8. SliceOwner — pooled, disposable Slices\n\n`SliceOwner` is a rented `Slice` that returns its buffer to an `ArrayPool<byte>` on `Dispose` — the allocation-free analogue of `IMemoryOwner<byte>`. The contract: **you MUST `Dispose` it, and MUST NOT use its data afterward.**\n\n```csharp\nusing (var owner = Slice.FromBytes(payload, ArrayPool<byte>.Shared))\n{\n    Slice data = owner.Data;     // valid only inside the using\n    Use(data.Span);\n}   // buffer returned to the pool here\n```\n\n`owner.IsValid`, `owner.Count`, `owner.Span`, `owner.Pool`; `SliceOwner.Wrap/Create/Copy` and `writer.ToSliceOwner()` produce them. Don't let an owner's `Data` escape the `using`.\n\n## 9. Span / Memory interop & `ISpanEncodable`\n\n`Slice` interops freely with the modern primitives: `slice.Span` (`ReadOnlySpan<byte>`), `slice.Memory` (`ReadOnlyMemory<byte>`), `byte[].AsSlice()`. Many hot types (keys, values, the writers) implement **`ISpanEncodable`** so they can be rendered into a caller's buffer with no intermediate `Slice` allocation — `TryGetSpan(out span)` / `TryGetSizeHint(out size)` / `TryEncode(dest, out written)`. That interface is how `subspace.Key(...)`/`FdbValue.*` write themselves into pooled buffers at the last moment.\n\nFor working directly over `Span<byte>` (a caller-owned, fixed buffer) instead of `Slice`, use `SpanReader`/`SpanWriter` — see [`references/span-readers-writers.md`](references/span-readers-writers.md).\n\n## 10. Round-trip example\n\n```csharp\n// build\nvar w = new SliceWriter();\nw.WriteInt32(order.Id);\nw.WriteVarString(order.Customer);\nw.WriteVarInt64(order.Total);\nSlice packed = w.ToSlice();\n\n// parse\nvar r = packed.ToSliceReader();\nint id        = r.ReadInt32();\nstring cust   = r.ReadVarString();\nlong total    = (long) r.ReadVarInt64();\n```\n\n## 11. Self-check\n\n- [ ] Did I use `IsNull`/`IsNullOrEmpty` (not `== Slice.Empty`) to test for a missing value?\n- [ ] Am I treating `Slice` as a **view** — copying with `ToArray()`/`ToSliceOwner()` before mutating shared arrays or outliving a pooled buffer?\n- [ ] Did I pick the right integer encoding (`Fixed*`/`*BE` for sortable keys; `VarInt*`/`Fixed*` for self-delimiting stream fields; `FromInt32` only for standalone whole-slice values)?\n- [ ] Do my `SliceWriter` writes and `SliceReader` reads pair up (`WriteInt32`↔`ReadInt32`, `VarInt`↔`VarInt`, `VarString`↔`VarString`)?\n- [ ] If I rented from an `ArrayPool` (`SliceWriter(pool)` / `SliceOwner`), did I `Dispose`/`ToSliceOwner()` so the buffer returns to the pool — and not use the data after disposal?\n","tagline":"How to correctly use the Slice type and its companions (SliceReader, SliceWriter, SliceOwner) for binary data in the FoundationDB .NET client / SnowBank.Core codebase.
