Struct ComputableResult 

pub struct ComputableResult<T, C: Computable<T>> { /* private fields */ }

A result-like object that stores the result of a Computable for later use.

Implementations

impl<T, C: Computable<T>> ComputableResult<T, C>

pub fn new(computable: C) -> Self

Create a new ComputableResult from an instance of Computable.

pub fn try_compute(&mut self) -> Completable<&T>

Advance the inner Computable and return its result or return a reference to the already computed result.

pub fn result_ref(&self) -> Option<&T>

A reference to the computed result, assuming it is already available.

pub fn result(self) -> Option<T>

The computed result, assuming it is already available.

pub fn computable_ref(&self) -> &C

A reference to the underlying computation, assuming it is still available.

pub fn computable(self) -> C

The underlying computation, assuming it is still available.

Trait Implementations

impl<T: Clone, C: Clone + Computable<T>> Clone for ComputableResult<T, C>

fn clone(&self) -> ComputableResult<T, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, C: Debug + Computable<T>> Debug for ComputableResult<T, C>

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

Formats the value using the given formatter.

impl<T, C: Computable<T>> From<C> for ComputableResult<T, C>

fn from(value: C) -> Self

Converts to this type from the input type.

impl<T: PartialEq, C: PartialEq + Computable<T>> PartialEq for ComputableResult<T, C>

fn eq(&self, other: &ComputableResult<T, C>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
