Struct rustc_hir::def::PerNS

pub struct PerNS<T> {
    pub value_ns: T,
    pub type_ns: T,
    pub macro_ns: T,
}

Just a helper ‒ separate structure for each namespace.

Fields

value_ns: T

type_ns: T

macro_ns: T

Implementations

impl<T> PerNS<T>

pub fn map<U, F: FnMut(T) -> U>(self, f: F) -> PerNS<U>

pub fn into_iter(self) -> IntoIter<T, 3>

pub fn iter(&self) -> IntoIter<&T, 3>

impl<T> PerNS<Option<T>>

pub fn is_empty(&self) -> bool

Returns true if all the items in this collection are None.

Returns an iterator over the items which are Some.

Trait Implementations

impl<T: Clone> Clone for PerNS<T>

fn clone(&self) -> PerNS<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for PerNS<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for PerNS<T>

fn default() -> PerNS<T>

Returns the “default value” for a type.

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<T: Copy> Copy for PerNS<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
