icydb-primitives

Shared primitive metadata and scalar capability classification for IcyDB.

This crate defines canonical scalar registry data used by schema and runtime layers (for example ScalarKind, ScalarMetadata, and coercion-family metadata).

Use this crate when tooling or internal components need stable scalar capability information.

Boundary

icydb-primitives owns scalar capability metadata that must stay shared across schema and runtime layers: scalar kind identity, coercion family, numeric-coercion support, arithmetic/equality/ordering support, query keyability, and storage-key encodability.

Schema-only trait-generation policy stays outside this crate. Decisions such as which generated Rust traits a schema wrapper derives, whether a primitive supports %, Copy, or Hash, and how schema macro inputs map onto concrete Rust types remain owned by icydb-schema / icydb-schema-derive until they are explicitly promoted into shared scalar metadata.
