Enum Provenance 

pub enum Provenance {
    Position(SourcePosition),
    LeanMetadata {
        key: String,
        value: String,
    },
}

The transparent carrier’s payload: a binder’s kind, or where a subterm came from. Where a subterm came from.

Variants

Position(SourcePosition)

A position in a source text.

LeanMetadata

One entry of a Lean Expr.mdata map: its key, and the exporter’s rendering of its DataValue (Lean.DataValue.ofBool true).

Fields

key: String

The metadata key (noImplicitLambda, _inaccessible, pp.analysis, …).

value: String

The value, as the exporter spells it.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Provenance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Provenance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Provenance

fn eq(&self, other: &Provenance) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Provenance

impl StructuralPartialEq for Provenance
