Struct ComputableIdentity 

pub struct ComputableIdentity<T> { /* private fields */ }

A trivial Computable that immediately returns a pre-computed value.

This is useful for wrapping an already-computed value in the Computable interface, allowing it to be used in contexts that expect a computation.

After the value is returned once, subsequent calls to Computable::try_compute will return Incomplete::Exhausted.

Example

use computation_process::{ComputableIdentity, Computable};

let mut identity: ComputableIdentity<i32> = 42.into();
assert_eq!(identity.try_compute(), Ok(42));

Trait Implementations

impl<T: Clone> Clone for ComputableIdentity<T>

fn clone(&self) -> ComputableIdentity<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Computable<T> for ComputableIdentity<T>

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

Try to advance this computation, returning a value once the computation is done.

fn compute_completable(&mut self) -> Completable<T>

Advance this computation until it either completes, is canceled, or becomes exhausted, skipping over all suspended states.

fn compute(&mut self) -> Cancellable<T>

Advance this computation until completion, skipping over all suspended states.

fn dyn_computable(self) -> DynComputable<T>

where Self: Sized + 'static,

Utility method to convert this Computable to a dynamic type.

impl<T: Debug> Debug for ComputableIdentity<T>

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

Formats the value using the given formatter.

impl<T> From<T> for ComputableIdentity<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for ComputableIdentity<T>

fn eq(&self, other: &ComputableIdentity<T>) -> 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.
