//! Thin wrappers around bincode 2.x that preserve the bincode 1.x wire format
//! and 1.x-style `serialize`/`deserialize` ergonomics for existing call sites.
//!
//! The on-disk format produced by [`serialize`] is byte-compatible with
//! bincode 1.3's default config (fixed-int, little-endian, no length limit) so
//! existing git blobs, RocksDB rows, and proximity index snapshots written by
//! older versions of this crate continue to round-trip.
