reddb-io-server 1.12.0

//! Server-side adapter for the legacy RedDB binary protocol.
//!
//! The byte-level contract lives in `reddb-wire::legacy`. This module
//! only converts between protocol `WireValue` and engine `Value`.

use crate::storage::schema::Value;
use reddb_wire::legacy::WireValue;

// The `WireValue`<->`Value` conversion impls moved to `reddb-wire`'s
// `legacy` module (ADR 0052, #1061): once `Value` was re-homed to the
// keystone crate below wire, the orphan rule required those impls to live
// in `WireValue`'s home crate. The helper functions below still drive the
// legacy codec and rely on those impls being in scope via `reddb_wire`.
