Struct hir_ty::OverloadedDeref

pub struct OverloadedDeref(pub Option<Mutability>);

An overloaded autoderef step, representing a Deref(Mut)::deref(_mut) call, with the signature &'a T -> &'a U or &'a mut T -> &'a mut U. The target type is U in both cases, with the region and mutability being those shared by both the receiver and the returned reference.

Mutability is None when we are not sure.

Trait Implementations

impl Clone for OverloadedDeref

fn clone(&self) -> OverloadedDeref

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OverloadedDeref

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

Formats the value using the given formatter.

impl Hash for OverloadedDeref

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 PartialEq for OverloadedDeref

fn eq(&self, other: &OverloadedDeref) -> 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.
