Enum rustc_resolve::ModuleOrUniformRoot

pub(crate) enum ModuleOrUniformRoot<'a> {
    Module(Module<'a>),
    CrateRootAndExternPrelude,
    ExternPrelude,
    CurrentScope,
}

Variants

Module(Module<'a>)

Regular module.

CrateRootAndExternPrelude

Virtual module that denotes resolution in crate root with fallback to extern prelude.

ExternPrelude

Virtual module that denotes resolution in extern prelude. Used for paths starting with :: on 2018 edition.

CurrentScope

Virtual module that denotes resolution in current scope. Used only for resolving single-segment imports. The reason it exists is that import paths are always split into two parts, the first of which should be some kind of module.

Trait Implementations

impl<'a> Clone for ModuleOrUniformRoot<'a>

fn clone(&self) -> ModuleOrUniformRoot<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ModuleOrUniformRoot<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ModuleOrUniformRoot<'a>

fn eq(&self, other: &ModuleOrUniformRoot<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Copy for ModuleOrUniformRoot<'a>

impl<'a> StructuralPartialEq for ModuleOrUniformRoot<'a>

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.
