Enum CompileProvenance 

#[non_exhaustive]
pub enum CompileProvenance {
    ExactAst,
    DesugaredAst,
    DynamicBoundary,
}

Provenance for HIR-local compile-environment facts.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ExactAst

Fact came directly from parser AST syntax.

DesugaredAst

Fact came from a simple compile-time desugaring.

DynamicBoundary

Fact came from conservative dynamic-boundary classification.

Trait Implementations

impl Clone for CompileProvenance

fn clone(&self) -> CompileProvenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompileProvenance

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

Formats the value using the given formatter.

impl Hash for CompileProvenance

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompileProvenance

fn eq(&self, other: &CompileProvenance) -> 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.
