Struct EagerFuture 

pub struct EagerFuture<C> { /* private fields */ }

A cell whose value is seeded with a task scheduled at EagerFutureCell::new, in the background.

Use EagerFutureCell or MutEagerFutureCell, directly.

Implementations

impl<T: Clone + Send + Sync + 'static> EagerFuture<Mutex<RawMutex, Option<T>>>

pub fn overwrite(&self, value: T)

Force value into the cell, aborting the background future so its (now-superseded) result is discarded. Any current or future get observes value.

impl<C: ResultCell> EagerFuture<C>

pub fn new<Fut>(work: Fut, handle: &Handle) -> Self

where Fut: Future<Output = C::Value> + Send + 'static,

Initialize the cell with the given work future, starting the work immediately on handle.

pub async fn get(&self) -> C::Value

Fetch a clone of the value, awaiting the work if necessary.

Trait Implementations

impl<C> Clone for EagerFuture<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C> Debug for EagerFuture<C>

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

Formats the value using the given formatter.
