Struct CljxFuture 

pub struct CljxFuture {
    pub state: Mutex<FutureState>,
    pub cond: Condvar,
    /* private fields */
}

A future value computed asynchronously on another thread.

Fields

cond: Condvar

Implementations

impl CljxFuture

pub fn new() -> Self

pub fn is_done(&self) -> bool

True if done, failed, or cancelled (not still running).

pub fn is_cancelled(&self) -> bool

True if explicitly cancelled.

pub fn cancel(&self) -> bool

Mark a still-running future cancelled, waking anyone waiting on it.

Returns false when it had already settled. The task itself is not interrupted; what is cancelled is the result.

pub fn cancelled_error() -> Value

The catchable value every reader of a cancelled future raises.

One shape for every path — the sync tree-walker’s await/deref, the async tree-walker, and the compiled state machine all hand user code the same ex-info-like error, so a catch behaves the same whether or not the enclosing fn happened to be async-JIT-compiled.

pub fn mark_observed(&self)

Mark this future’s result as observed. Call when a consumer reads the settled value (await/deref), so a later drop doesn’t warn about an unobserved error.

Trait Implementations

impl Debug for CljxFuture

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

Formats the value using the given formatter.

impl Default for CljxFuture

fn default() -> Self

Returns the “default value” for a type.

impl Drop for CljxFuture

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Trace for CljxFuture

fn trace(&self, visitor: &mut MarkVisitor)

fn gc_size_extra(&self) -> usize
