pub(crate) struct BindingKey {
    pub(crate) ident: Ident,
    pub(crate) ns: Namespace,
    pub(crate) disambiguator: u32,
}
Expand description

A key that identifies a binding in a given Module.

Multiple bindings in the same module can have the same key (in a valid program) if all but one of them come from glob imports.

Fields§

§ident: Ident

The identifier for the binding, always the normalize_to_macros_2_0 version of the identifier.

§ns: Namespace§disambiguator: u32

0 if ident is not _, otherwise a value that’s unique to the specific _ in the expanded AST that introduced this binding.
