Enum NameRefClass

pub enum NameRefClass<'db> {
    Definition(Definition, Option<GenericSubstitution<'db>>),
    FieldShorthand {
        local_ref: Local,
        field_ref: Field,
        adt_subst: GenericSubstitution<'db>,
    },
    ExternCrateShorthand {
        decl: ExternCrateDecl,
        krate: Crate,
    },
}

This is similar to NameClass, but works for [ast::NameRef] rather than for [ast::Name]. Similarly, what looks like a reference in syntax is a reference most of the time, but there are a couple of annoying exceptions.

A model special case is field shorthand syntax, which uses a single reference to point to two different defs.

Variants

Definition(Definition, Option<GenericSubstitution<'db>>)

FieldShorthand

Fields

local_ref: Local

field_ref: Field

adt_subst: GenericSubstitution<'db>

ExternCrateShorthand

The specific situation where we have an extern crate decl without a rename Here we have both a declaration and a reference.

extern crate foo;

Fields

decl: ExternCrateDecl

krate: Crate
