Struct dereffer::DerefsToMut

pub struct DerefsToMut<Inner, Ref: ?Sized> { /* private fields */ }

Similar to DerefsTo, but supports mutable dereferencing too.

Because Ruse doesn’t offer a way to abstract over mutability, i.e., accept both &T and &mut T, this struct must handle the Deref and DerefMut cases separately with individual functions.

Implementations

impl<Inner, Ref: ?Sized> DerefsToMut<Inner, Ref>

pub const fn new( inner: Inner, deref_func: fn(_: &Inner) -> &Ref, deref_mut_func: fn(_: &mut Inner) -> &mut Ref ) -> Self

Creates a new wrapper with custom arbitrary deref functions.

impl<Inner, Ref> DerefsToMut<Inner, Ref>where Inner: DerefMut<Target = Ref>, Ref: ?Sized,

pub const fn new_default(inner: Inner) -> Self

Creates a new wrapper with default, simple deref functions, Deref::deref() and DerefMut::deref_mut().

Trait Implementations

impl<Inner, Ref: ?Sized> Deref for DerefsToMut<Inner, Ref>

type Target = Ref

The resulting type after dereferencing.

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

Dereferences the value.

impl<Inner, Ref: ?Sized> DerefMut for DerefsToMut<Inner, Ref>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
