@peerbit/any-store-rust

Rust-backed AnyStore implementation for Peerbit.

This package is experimental and opt-in. The first implementation keeps the hot key/value map in Rust, persists stores through an append-only operation log plus compacted snapshots where the file backend supports safe replacement, and preserves the existing AnyStore API surface.

The implementation keeps the live key/value map in Rust and uses a compact binary WAL over a small persistence backend. Node uses fs and browsers use OPFS sync access handles when the store runs in a dedicated worker.

The OPFS backend uses two manifest slots with checksums for checkpoints. A new snapshot and empty journal are flushed before the inactive manifest slot is updated, so a torn manifest write falls back to the previous valid checkpoint instead of shadowing committed WAL records.

RustAnyStore also exposes putMany, getMany, and delMany as opt-in batch helpers. They are not part of the shared AnyStore interface yet, but they let callers collapse many KV operations into one Rust/WASM call.
