Enum rustfst::algorithms::lazy::cache::cache_status::CacheStatus

pub enum CacheStatus<T> {
    NotComputed,
    Computed(T),
}

This enumeration represents the computation status in a cache.

Variants

NotComputed

Computed(T)

Implementations

impl<T> CacheStatus<T>

pub fn map<U, F: FnOnce(T) -> U>(self, f: F) -> CacheStatus<U>

Map the computed value and returned it as a cache status.

pub fn and<U>(self, other: CacheStatus<U>) -> CacheStatus<U>

Returns NotComputed if self is not computed otherwise it returns other.

pub fn and_then<U>(self, f: impl FnOnce(T) -> CacheStatus<U>) -> CacheStatus<U>

Chain lazyly two CacheStatus and flatten them.

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

Convert into an Option. Some if computed otherwise None.

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

Convert to an Option. Some if computed otherwise None.

pub fn is_computed(&self) -> bool

Return true if CachStatus is computed.

pub fn is_not_computed(&self) -> bool

Return true if CachStatus is not computed.

pub fn or(self, other: CacheStatus<T>) -> CacheStatus<T>

If the value is already computed, self is returned otherwise other is returned.

If a lazy implementation is preferable, call or_else.

pub fn or_else(self, f: impl FnOnce() -> CacheStatus<T>) -> CacheStatus<T>

Trait Implementations

impl<T: Clone> Clone for CacheStatus<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for CacheStatus<T>

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

Formats the value using the given formatter.

impl<T> From<Option<T>> for CacheStatus<T>

fn from(v: Option<T>) -> Self

Converts to this type from the input type.

impl<T: Eq> PartialEq for CacheStatus<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: Copy> Copy for CacheStatus<T>
