Struct bones_framework::lib::prelude::borrow::AtomicBorrowMut
pub struct AtomicBorrowMut<'a> { /* private fields */ }
Expand description
Encapsulates exclusive borrowing state.
An instance of this type guarantees that neither AtomicBorrowMut
, nor AtomicBorrow
cannot be constructed for the same lock.
Implementations§
§impl<'a> AtomicBorrowMut<'a>
impl<'a> AtomicBorrowMut<'a>
pub fn try_new(lock: &'a AtomicIsize) -> Option<AtomicBorrowMut<'a>>
pub fn try_new(lock: &'a AtomicIsize) -> Option<AtomicBorrowMut<'a>>
Attempts to borrow lock mutably.
pub unsafe fn restore_leaked(lock: &'a AtomicIsize) -> AtomicBorrowMut<'a>
pub unsafe fn restore_leaked(lock: &'a AtomicIsize) -> AtomicBorrowMut<'a>
Restore previously leaked AtomicBorrowMut
instance.
This method should be called only after forgetting AtomicBorrowMut
instance.
Or after locking manually using try_borrow_mut
method.
pub fn dummy() -> AtomicBorrowMut<'a>
pub fn dummy() -> AtomicBorrowMut<'a>
Returns dummy atomic borrow that doesn’t actually locks anything.
It is used within RefMut::new
method that take external reference.
pub fn clone(&self) -> AtomicBorrowMut<'a>
pub fn clone(&self) -> AtomicBorrowMut<'a>
Borrows can be cloned.
Mutable borrows are cloned when borrowed reference is split into disjoint parts.
There is a hard limit on number of clones for each lock (except dummy lock) and it will panic if cloning fails.
Huge limit value makes it practically unreachable without forget
ing clones in a loop.
