[−][src]Module ambience::thread

Structs

Guard value for ambient data that was passed to set(). When AmbientGuard is dropped, the value passed to set() is removed from the ambient data stack and is no longer accessible.

Functions

get	Retrieves thread-local ambient data of type `T` that was previously set on the same thread. The returned value will always be the most recently `set` value whose `AmbientGuard` still exists.
has	Returns `true` if ambient data of type `T` is set on the current thread.
set	Sets thread-local ambient data of type `T`. The value can be accessed on the same thread until the returned `AmbientGuard` is dropped.
set_rc	Sets thread-local ambient data of type `T`. Works like `set`, except the given `Rc` will be reused internally. Useful in cases where you already have a `Rc` and don't want to clone its contents.
