Crate dmc_diagnostic 

User-facing walkthrough: ../../dmc-docs/dmc-diagnostic/ Run cargo doc --open -p dmc-diagnostic for the inline rustdoc. Unified diagnostic codes for the dmc pipeline.

Every layer (lexer, parser, transform, codegen) emits into one shared DiagnosticEngine<Code>. Per-layer variants are gated behind cargo features so a crate that only needs lexer codes can opt out of the rest.

Feature flags

• lexer - E*** lexer-emitted variants
• parser - P*** / PW*** parser-emitted variants
• transform - T*** / TW*** transform-emitted variants
• codegen - G*** / GW*** codegen-emitted variants

A normal full build (e.g. via dmc-core) enables all features.

Code

Stable, machine-readable diagnostic identifiers spanning the whole pipeline. Codes use disjoint string namespaces per layer:

Canonical fallible-return type across the dmc pipeline.
