Trait Send

pub unsafe auto trait Send { }

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.

where T: ?Sized,

impl<T> !Send for *mut T

where 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,

A MutexGuard is not Send to maximize platform portablity.

On platforms that use POSIX threads (commonly referred to as pthreads) there is a requirement to release mutex locks on the same thread they were acquired. For this reason, MutexGuard must not implement Send to prevent it being dropped from another thread.

where T: ?Sized,

impl<T> !Send for MappedRwLockWriteGuard<'_, T>

impl<T> Send for Mutex<T>

where T: Send + ?Sized,
