Crate ctx [−] [src]

Structs

A Context carries a deadline, a cancelation Future, and other values across API boundaries.

background	Returns an empty Context. It is never canceled has neither a value nor a deadline. It is typically used as a top-level Context.
with_cancel	Returns a copy of parent as a new future, which is closed when the returned cancel function is called or when the parent context's future is resolved – whichever happens first.
with_deadline	Returns `with_timeout(parent, deadline - Instant::now())`.
with_timeout	Returns a copy of the parent context with the given deadline associated to it. The returned context's future resolves when the deadline expires, the returned cancel function is called, or when the parent context's future resolves – whichever happens first.
with_value	Returns a copy of parent, but with the given value associated to it.
