Struct rustc_resolve::BindingKey

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

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.

Trait Implementations

impl Clone for BindingKey

fn clone(&self) -> BindingKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BindingKey

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

Formats the value using the given formatter.

impl Hash for BindingKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<BindingKey> for BindingKey

fn eq(&self, other: &BindingKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

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.
