Enum rustc_hir::def::Namespace

pub enum Namespace {
    TypeNS,
    ValueNS,
    MacroNS,
}

Different kinds of symbols can coexist even if they share the same textual name. Therefore, they each have a separate universe (known as a “namespace”).

Variants

TypeNS

The type namespace includes structs, enums, unions, traits, and mods (and, by extension, crates).

Note that the type namespace includes other items; this is not an exhaustive list.

ValueNS

The value namespace includes fns, consts, statics, and local variables (including function arguments).

MacroNS

The macro namespace includes macro_rules! macros, declarative macros, procedural macros, attribute macros, derive macros, and non-macro attributes like #[inline] and #[rustfmt::skip].

Implementations

impl Namespace

pub fn descr(self) -> &'static str

The English description of the namespace.

Trait Implementations

impl Clone for Namespace

fn clone(&self) -> Namespace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl Hash for Namespace

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<T> Index<Namespace> for PerNS<T>

type Output = T

The returned type after indexing.

fn index(&self, ns: Namespace) -> &T

Performs the indexing (container[index]) operation.

impl<T> IndexMut<Namespace> for PerNS<T>

fn index_mut(&mut self, ns: Namespace) -> &mut T

Performs the mutable indexing (container[index]) operation.

impl PartialEq<Namespace> for Namespace

fn eq(&self, other: &Namespace) -> 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.

impl Copy for Namespace

impl Eq for Namespace

impl StructuralEq for Namespace

impl StructuralPartialEq for Namespace

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.
