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<__D: SpanDecoder> Decodable<__D> for Namespace

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for Namespace

fn encode(&self, __encoder: &mut __E)

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<__CTX> HashStable<__CTX> for Namespace

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

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 Ord for Namespace

fn cmp(&self, other: &Namespace) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Namespace

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

fn partial_cmp(&self, other: &Namespace) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<CTX: HashStableContext> ToStableHashKey<CTX> for Namespace

type KeyType = Namespace

fn to_stable_hash_key(&self, _: &CTX) -> Namespace

impl Copy for Namespace

impl Eq 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.
