oxisqlite Pure-Rust SQLite-compatible engine (C-free fork of limbo)
Documentation

oxisqlite

Top-level facade of the C-free oxisqlite engine — a Pure-Rust fork of limbo 0.0.22, internal to the OxiSQL workspace.

This crate re-exports the engine's public surface — Connection, Statement, positional and named parameter binding (params / params_from_iter / named_params!, covering :name / @name / $name / #name placeholder forms), and the value/Value types — and is the entry point consumed by the oxisql-sqlite-compat backend. It is a thin, ergonomic wrapper over oxisqlite-core; all bytecode execution, storage, and SQL processing live there.

Database::open_from_bytes(bytes) additionally opens a shareable Database directly from an in-memory SQLite image — e.g. include_bytes!, VACUUM INTO, or sqlite3_serialize() output — mirroring SQLite's sqlite3_deserialize(). No temporary file is involved, so it works under WASI, in a browser, or on a read-only filesystem; the returned Database can be connect()ed multiple times, and all connections share the same preloaded image. Malformed input (too short, wrong magic, or an invalid page size) is a typed error, never a panic.

  • Role: engine facade (Connection, Statement, params, value types).
  • Version: 0.3.3 (2026-07-17).
  • Tests: 38 passing (default features and --all-features), 0 failed (verified 2026-07-17).
  • Approx LOC: ~1,900 (tokei src/; up from ~973 pre-0.3.3 — this release added open_from_bytes and full named-parameter binding with Cow<'static, str> keys).
  • Pure Rust / no C: 100% safe, portable Rust. No C allocator, no C parser generator, no cc / build.rs. CC=/usr/bin/false cargo build succeeds.
  • Internal: engine-internal member of the OxiSQL workspace (the entry point consumed by oxisql-sqlite-compat); independently published on crates.io like every other oxisqlite-* crate (no publish = false; live since v0.1.0, 2026-06-11).
