T: ?Sized;
Expand description
A mutable value with borrowing checked at runtime
Implementations§
source§impl<T> KCell<T>where
T: ?Sized,
impl<T> KCell<T>where
T: ?Sized,
sourcepub fn borrow(&self) -> Borrow<'_, T>
pub fn borrow(&self) -> Borrow<'_, T>
Immutably borrows the wrapped value.
Multiple immutable borrows can be made at the same time.
If the value is currently mutably borrowed then this function will block.
See try_borrow
for a non-blocking version.
sourcepub fn try_borrow(&self) -> Option<Borrow<'_, T>>
pub fn try_borrow(&self) -> Option<Borrow<'_, T>>
Attempts to mutably borrow the wrapped value.
Returns an error if the value is currently mutably borrowed.
sourcepub fn borrow_mut(&self) -> BorrowMut<'_, T>
pub fn borrow_mut(&self) -> BorrowMut<'_, T>
Mutably borrows the wrapped value.
If the value is currently borrowed then this function will block until the value can be
locked.
See try_borrow_mut
for a non-blocking version.
sourcepub fn try_borrow_mut(&self) -> Option<BorrowMut<'_, T>>
pub fn try_borrow_mut(&self) -> Option<BorrowMut<'_, T>>
Attempts to mutably borrow the wrapped value.
Returns an error if the value is currently mutably borrowed.
