Struct RefMapMut

pub struct RefMapMut<'a, T: 'a> { /* private fields */ }

Implementations

impl<'a, T: 'a> RefMapMut<'a, T>

pub fn new(borrow: Exclusive<'a>, value: T) -> Self

pub fn map_into<K: 'a, F: FnMut(&mut T) -> K>(self, f: F) -> RefMapMut<'a, K>

pub unsafe fn deconstruct(self) -> (Exclusive<'a>, T)

Deconstructs this mapped borrow to its underlying borrow state and value.

Safety

Ensure that you still follow all safety guidelines of this mutable mapped ref.

Trait Implementations

impl<'a, T: 'a> AsMut<T> for RefMapMut<'a, T>

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a, T: 'a> AsRef<T> for RefMapMut<'a, T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, T: 'a> Borrow<T> for RefMapMut<'a, T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<'a, T: Debug + 'a> Debug for RefMapMut<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: 'a> Deref for RefMapMut<'a, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a, T: 'a> DerefMut for RefMapMut<'a, T>

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

Mutably dereferences the value.
