Struct BackendDiagnosticMetadata 

pub struct BackendDiagnosticMetadata { /* private fields */ }

Stable presentation metadata for one native backend failure.

The metadata is deliberately smaller than the backend’s error enum. The native backend remains the owner of the typed error and its platform details; this value gives adapters a stable code and, when applicable, the portable configuration field that caused the failure.
