Enum PirAnchorKind 

#[non_exhaustive]
pub enum PirAnchorKind {
    ExplicitSource,
    SourceBackedGenerated,
    GeneratedNoSource,
    DynamicBoundary,
    AmbientInput,
    Unknown,
}

Provenance class for a PIR node’s source anchor.

Every source-derived node anchors to the workspace range that caused it. Generated, framework, or ambient nodes only exist when their provenance is explicit, so a provider can never mistake a modeled fact for source text.

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.

ExplicitSource

Node anchors directly to source text.

SourceBackedGenerated

Node anchors to a framework declaration, not a fabricated method body.

GeneratedNoSource

Generated node with no source backing; receipt-only.

DynamicBoundary

Node anchors to a dynamic boundary range when available.

AmbientInput

Node reports an ambient-input class rather than source text.

Unknown

Fallback node whose anchor could not be classified.

Implementations

impl PirAnchorKind

pub const fn name(self) -> &'static str

Stable name used in receipts and snapshots.

pub const fn is_source_backed(self) -> bool

Whether a node with this anchor kind is expected to carry a source range.

Trait Implementations

impl Clone for PirAnchorKind

fn clone(&self) -> PirAnchorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PirAnchorKind

impl Debug for PirAnchorKind

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

Formats the value using the given formatter.

impl Eq for PirAnchorKind

impl Hash for PirAnchorKind

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 PirAnchorKind

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