Struct rustc_ap_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> 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: Debug> Debug for PtrKey<'a, T>

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

Formats the value using the given formatter.

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

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

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

fn eq(&self, rhs: &Self) -> 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 !=.
