pub(crate) enum ModuleKind {
    Block,
    Def(DefKind, DefId, Symbol),
}

Variants§

§

Block

An anonymous module; e.g., just a block.

fn main() {
    fn f() {} // (1)
    { // This is an anonymous module
        f(); // This resolves to (2) as we are inside the block.
        fn f() {} // (2)
    }
    f(); // Resolves to (1)
}
§

Def(DefKind, DefId, Symbol)

Any module with a name.

This could be:

  • A normal module – either mod from_file; or mod from_block { } – or the crate root (which is conceptually a top-level module). Note that the crate root’s name will be kw::Empty.
  • A trait or an enum (it implicitly contains associated types, methods and variant constructors).
