Enum GlobalProvenance 

pub enum GlobalProvenance {
    Global(GlobalDeclRef),
    Function(FnPtr, Ty),
    TypeId(Ty),
}

Provenance is the location in memory a pointer (or the byte of a pointer, see Byte) points to. GlobalProvenance represents a compile-time provenance. See https://doc.rust-lang.org/std/ptr/index.html#provenance

Variants

Global(GlobalDeclRef)

Function(FnPtr, Ty)

A function, with the type of function pointers to it.

TypeId(Ty)

The allocation backing the TypeId of this type. Note that TypeIds always have 16 bytes worth of provenance, regardless of the platform’s pointer size, so Byte::Provenance’s byte index can go up to 16! In other words, the bytes of a full TypeId are Provenance(TypeId(ty), 0, 0..16).

Trait Implementations

impl AstVisitable for GlobalProvenance

fn drive<V: VisitAst>(&self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_mut<V: VisitAstMut>(&mut self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

fn drive_two<V: ZipAst>(&self, other: &Self, v: &mut V) -> ControlFlow<V::Break>

Recursively visit this type with the provided visitor. This calls the visitor’s visit_$any method if it exists, otherwise visit_inner.

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

The name of the type, used for debug logging.

fn dyn_visit<T: AstVisitable>(&self, f: impl FnMut(&T))

where Self: Sized,

Visit all occurrences of that type inside self, in pre-order traversal.

fn dyn_visit_mut<T: AstVisitable>(&mut self, f: impl FnMut(&mut T))

where Self: Sized,

Visit all occurrences of that type inside self, in pre-order traversal.
