Struct ErrorDescriptor 

pub struct ErrorDescriptor { /* private fields */ }

Immutable catalog metadata for one canonical error identity.

A descriptor owns stable identity, classification, fault attribution, component ownership, the fixed public message, operational policy, public exposure, backtrace capture, and explicit boundary projections. Its ordered field schemas define the only context accepted by descriptor-aware views. Catalog consumers can inspect this metadata but cannot construct or modify descriptors outside this crate.

    BacktracePolicy, CanonicalCondition, ComponentId, ErrorClass, ErrorCode,
    ErrorDescriptor, ErrorSeverity, Exposure, FaultAttribution, RecoveryHint,
};

let descriptor = ErrorDescriptor {
    code: ErrorCode::try_new("example.operation.failed").unwrap(),
    class: ErrorClass::INTERNAL,
    condition: CanonicalCondition::Internal,
    fault: FaultAttribution::Unknown,
    component: ComponentId::CORE,
    public_message: "The operation failed",
    severity: ErrorSeverity::Error,
