Struct bones_framework::prelude::borrow::AtomicBorrow

pub struct AtomicBorrow<'a> { /* private fields */ }
Expand description

Encapsulates shared borrowing state.

An instance of this type guarantees that AtomicBorrowMut cannot be constructed for the same lock.

Implementations§

§

impl<'a> AtomicBorrow<'a>

pub fn try_new(lock: &'a AtomicIsize) -> Option<AtomicBorrow<'a>>

Attempts to borrow lock immutably.

Fails if Lock contains a value for which is_writing returns true.

On success Lock contains value for which is_reading returns true.

pub unsafe fn restore_leaked(lock: &'a AtomicIsize) -> AtomicBorrow<'a>

Restore previously leaked AtomicBorrow instance.

This method should be called only after forgetting AtomicBorrow instance. Or after locking manually using try_borrow method.

pub fn dummy() -> AtomicBorrow<'a>

Returns dummy atomic borrow that doesn’t actually locks anything. It is used within Ref::new method that take external reference.

pub fn clone(&self) -> AtomicBorrow<'a>

Borrows can be cloned.

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.
