Struct Completion 

pub struct Completion(/* private fields */);

A lightweight in-process completion event.

Conceptually, a completion has an internal state of either unsignaled or signaled. Threads may wait on the completion until it achieves the signaled state, or alter its state.

On Fuchsia, this wraps sync_completion_t from zircon/system/ulib/sync.

Implementations

impl Completion

pub const fn new() -> Self

Creates a new completion in the unsignaled state.

pub fn wait(&self)

Blocks the current thread until the completion is signaled.

pub fn wait_for(&self, timeout: Duration) -> bool

Blocks the current thread until the completion is signaled or the timeout expires. Returns true if the completion was signaled, or false if it timed out.

pub fn wait_until(&self, deadline: MonotonicInstant) -> bool

Blocks the current thread until the completion is signaled or the deadline is reached. Returns true if the completion was signaled, or false if it timed out.

pub fn signal(&self)

Signals the completion, awakening all waiting threads.

pub fn reset(&self)

Resets the completion to the unsignaled state.

pub fn is_signaled(&self) -> bool

Returns true if the completion has been signaled.
