Struct rustc_data_structures::ptr_key::PtrKey

pub struct PtrKey<'a, T>(pub &'a T);

A wrapper around reference that compares and hashes like a pointer. Can be used as a key in sets/maps indexed by pointers to avoid unsafe.

Trait Implementations

impl<'a, T> Eq for PtrKey<'a, T>

impl<'a, T> Clone for PtrKey<'a, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T> PartialEq<PtrKey<'a, T>> for PtrKey<'a, T>

fn eq(&self, rhs: &Self) -> bool

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'a, T> Copy for PtrKey<'a, T>

impl<'a, T> Hash for PtrKey<'a, T>

fn hash<H: Hasher>(&self, hasher: &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<'a, T> Deref for PtrKey<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
