Module validation 

Central validation diagnostics for generation inputs and backend readiness.

Validation should happen between config/extraction resolution and backend emission. This module provides the shared diagnostic shape; individual validators can stay close to the subsystem they understand while returning structured reports here.

Structs

ValidatedApiSurface

Borrowed API surface that has passed central validation.

ValidationDiagnostic

One structured validation issue.

ValidationReport

Collected validation diagnostics.

Enums

ValidationCode

Stable validation diagnostic code.

ValidationSeverity

Validation severity.

Functions

is_critical_unsuppressible

Diagnostics that are never safe to suppress globally.

validate_api_surface

Validate the extracted public API surface before backend generation.

validate_api_surface_with_bridged_traits

Validate the extracted public API surface before backend generation, allowing excluded-type substitution only for traits with explicit bridge config.
