Struct Provenance 

pub struct Provenance { /* private fields */ }

Location from which a neutral-model value was derived.

Implementations

impl Provenance

pub const fn source(source: SourceId) -> Self

Creates provenance for an entire source.

pub const fn spanned(source: SourceId, span: SourceSpan) -> Self

Creates provenance for one byte range in a source.

pub const fn runtime_observation(source: SourceId) -> Self

Creates provenance for effective state observed from a runtime resource.

pub const fn user_override(source: SourceId) -> Self

Creates provenance for an explicit caller or user override.

pub const fn implementation_default(source: SourceId) -> Self

Creates provenance for a default introduced by a named implementation profile.

pub const fn conversion_decision(source: SourceId) -> Self

Creates provenance for a value chosen by an explicit conversion decision.

pub const fn kind(&self) -> ProvenanceKind

Returns how this origin entered the conversion plan.

pub const fn source_id(&self) -> &SourceId

Returns the source identity.

pub const fn span(&self) -> Option<SourceSpan>

Returns the optional byte range.
