Struct NativeFuture 

pub struct NativeFuture<T> { /* private fields */ }

A one-shot native completion exposed as a Rust future.

The future resolves to an Error when the operation fails, which for a command means it failed or was cancelled.

Native has accepted the operation by the time the call that returns this future returns, and runs it whether or not anything awaits the result. Dropping the future doesn’t cancel the operation; native still delivers and frees its result.

Implementations

impl<T> NativeFuture<T>

pub fn is_ready(&self) -> bool

Reports whether native has delivered the one terminal result.

pub fn wait(self) -> Result<T>

Blocks the calling thread until native delivers the result. An operation that completes only while this thread services it, such as a caller-driven render session’s release, needs wait_timeout or an executor instead.

pub fn wait_timeout(self, timeout: Duration) -> Result<Result<T>, Self>

Blocks the calling thread for at most timeout and returns the result, or gives the future back when the timeout ends first. This serves hosts that must pump another service loop between waits rather than run an async executor.

Trait Implementations

impl<T> Debug for NativeFuture<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Future for NativeFuture<T>

type Output = Result<T, Error>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, context: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
