reddb-io-types — the neutral keystone crate for RedDB's logical type
system (ADR 0052).
This crate sits at the bottom of the workspace crate graph: every
authority crate (reddb-io-file, reddb-io-wire, the planned
reddb-io-rql and reddb-io-crypto) may depend on it, but it depends on
no other workspace crate. It owns the core type vocabulary —
[Value], [DataType], [SqlTypeName], [TypeModifier],
[TypeCategory], [ValueError], and [Row] — together with the
[value_codec] serialization that Value::to_bytes/from_bytes delegate
to.
The reddb-server storage::schema module keeps a re-export shim so the
~180 existing call-sites across the workspace stay untouched.
