Enum ModuleKind

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).

Implementations

impl ModuleKind

pub(crate) fn name(&self) -> Option<Symbol>

Get name of the module.

Trait Implementations

impl Debug for ModuleKind

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
