Trait browser_window::prelude::rust_2024::Send
1.0.0 · source · pub unsafe auto trait Send { }Expand description
Types that can be transferred across thread boundaries.
This trait is automatically implemented when the compiler determines it’s appropriate.
An example of a non-Send type is the reference-counting pointer
rc::Rc. If two threads attempt to clone Rcs that point to the same
reference-counted value, they might try to update the reference count at the
same time, which is undefined behavior because Rc doesn’t use atomic
operations. Its cousin sync::Arc does use atomic operations (incurring
some overhead) and thus is Send.
See the Nomicon and the Sync trait for more details.
Implementors§
impl !Send for LocalWaker
impl !Send for Args
impl !Send for ArgsOs
impl Send for ApplicationHandleThreaded
impl Send for alloc::string::Drain<'_>
impl Send for Waker
impl<'a> Send for IoSlice<'a>
impl<'a> Send for IoSliceMut<'a>
impl<'a, H, R> Send for DelegateFuture<'a, H, R>where
R: Send,
§Safety
DelegateFuture by itself is not send.
This is because we keep a handle H, which is not necessarily Send.
However, because the closure only executes on the GUI thread,
and because the handle is only provided to the closure that will be
executed on the GUI thread, this should be fine.
impl<'a, R> Send for DelegateFutureFuture<'a, R>where
R: Send,
§Safety
DelegateFutureFuture by itself is not send.
This is because of ApplicationHandle.
However, because the closure only executes on the GUI thread,
and because this handle that is provided to the closure is something that
will only be sent with the closure to the GUI thread, this should be fine.
impl<Dyn> Send for DynMetadata<Dyn>where
Dyn: ?Sized,
impl<T> !Send for *const Twhere
T: ?Sized,
impl<T> !Send for *mut Twhere
T: ?Sized,
impl<T> !Send for NonNull<T>where
T: ?Sized,
NonNull pointers are not Send because the data they reference may be aliased.
impl<T> !Send for MappedMutexGuard<'_, T>where
T: ?Sized,
impl<T> !Send for MutexGuard<'_, T>where
T: ?Sized,
impl<T> !Send for ReentrantLockGuard<'_, T>where
T: ?Sized,
impl<T> !Send for MappedRwLockReadGuard<'_, T>where
T: ?Sized,
impl<T> !Send for MappedRwLockWriteGuard<'_, T>where
T: ?Sized,
impl<T> !Send for RwLockReadGuard<'_, T>where
T: ?Sized,
impl<T> !Send for RwLockWriteGuard<'_, T>where
T: ?Sized,
impl<T> Send for &T
impl<T> Send for ThinBox<T>
ThinBox<T> is Send if T is Send because the data is owned.
