How to correctly use the Slice type and its companions (SliceReader, SliceWriter, SliceOwner) for binary data in the FoundationDB .NET client / SnowBank.Core codebase. Slice is a readonly struct (namespace System) — the logical equivalent of a ReadOnlyMemory of bytes with many helpers. Use whenever code constructs or reads a Slice, converts between bytes and other types (Slice.FromBytes/FromStringUtf8/FromInt32/FromFixed64/ToInt64/ToStringUtf8/AsSlice/ToArray), builds or parses a binary buffer…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Slice, SliceReader, SliceWriter & friends `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. > **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. For 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). ## 1. Nil vs Empty — the #1 gotcha | | `Slice.Nil` | `Slice.Empty` | |---|---|---| …

How to install
mdr add snowbanksdk/foundationdb-dotnet-client/snowbank-slices-and-buffers@sha256:771c9daf38aa8c9dThe line at the top of this page pins the label git:20260621.01f75a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
