Crate valence_codegen 

Build-time code generation for Valence models from valence_schema! and valence_trait_schema! sources.

Pipeline

1. Trait pass — Collect *_valence_trait.rs (or your configured suffix), parse trait defs, emit shared trait definitions (see generate_from_trait_file in the internal codegen module).
2. Schema pass — For each *_valence_schema.rs, merge trait fields/connections, validate, then emit structs, connections, CRUD, query builder, metadata, and trait impls into one generated_models.rs via generate_models.

Where to read next

• build / build_with — one-liner host build.rs helpers.
• Internal codegen module — per-schema orchestration and generator dispatch.
• codegen::parser — shared valence_schema_dsl parse + lower into generator IR.
• codegen::generators — proc_macro2::TokenStream builders for each emitted surface area.

Structs

BuildOptions

Overrides for build_with.

CodegenConfig

Functions

build

Scan $CARGO_MANIFEST_DIR/schemas and write $OUT_DIR/generated_models.rs.
