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, 

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 Ord for Namespace

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

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 ==.

#[must_use]

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

This method tests for !=.

impl PartialOrd<Namespace> for Namespace

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

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