Struct thunk::sync::AtomicThunk

pub struct AtomicThunk<T> { /* fields omitted */ }

A thread-safe AtomicThunk, representing a lazily computed value.

TODO: Test Option<UnsafeCell<Cache<T>>> instead of storing thunk invalidation in the atomic flag.

Trait Implementations

impl<T: Send> Send for AtomicThunk<T>

impl<T: Sync> Sync for AtomicThunk<T>

impl<T> Drop for AtomicThunk<T>

fn drop(&mut self)

A method called when the value goes out of scope.

impl<T> AsRef<T> for AtomicThunk<T>

fn as_ref(&self) -> &T

Performs the conversion.

impl<T> AsMut<T> for AtomicThunk<T>

fn as_mut(&mut self) -> &mut T

Performs the conversion.

impl<T> Deref for AtomicThunk<T>

type Target = T

The resulting type after dereferencing

fn deref(&self) -> &T

The method called to dereference a value

impl<T> DerefMut for AtomicThunk<T>

fn deref_mut(&mut self) -> &mut T

The method called to mutably dereference a value

impl<T> From<T> for AtomicThunk<T>

fn from(t: T) -> AtomicThunk<T>

Performs the conversion.

impl<T> Lazy for AtomicThunk<T>

fn defer<F: FnBox() -> T + 'static>(f: F) -> AtomicThunk<T>

Defer a computation stored as a FnOnce closure. Unwrapping/dereferencing will force the computation of the closure.

fn force(&self)

Manually force a thunk's computation.

fn unwrap(self) -> T

Unwrap a thunk into its inner value. This forces the thunk.

fn computed(t: Self::Target) -> Self

Construct a thunk with a precomputed value. This means unwrapping/dereferencing is effectively a no-op.
