Struct Delay 

pub struct Delay {
    pub state: TrackedMutex<DelayState>,
    /* private fields */
}

A lazy computation with a cached result and retry after interruption.

Fields

state: TrackedMutex<DelayState>

Implementations

impl Delay

pub fn new(thunk: Box<dyn Thunk>) -> Self

pub fn force(&self) -> ValueResult<Value>

Force the delay and cache the result. Errors are as for LazySeq::try_realize.

pub fn is_realized(&self) -> bool

True if the delay has already been forced.

Trait Implementations

impl Debug for Delay

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

Formats the value using the given formatter.

impl Drop for Delay

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 Delay

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

fn gc_size_extra(&self) -> usize
