Struct bones_lib::ecs::atomic::borrow::AtomicBorrowMut

pub struct AtomicBorrowMut<'a> { /* private fields */ }

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>

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>

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>

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>

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 forgeting clones in a loop.

Trait Implementations

impl<'a> Drop for AtomicBorrowMut<'a>

fn drop(&mut self)

Executes the destructor for this type.
