Struct dfdi::Cached

pub struct Cached<'cx, S, P>where
    S: Service,
    P: Provider<'cx, S>,{ /* private fields */ }

Cached provider

A provider that calls the underlying provider on the first call and returns the result of that on all calls

Implementations

impl<'cx, S, P> Cached<'cx, S, P>where
    S: Service,
    P: Provider<'cx, S>,

pub fn new(provider: P) -> Self

Create a new cached provider

impl<'cx, S, F> Cached<'cx, S, F>where
    S: Service,
    F: Fn(&'cx Context<'_>) -> S::Output<'cx> + 'cx,

pub fn new_fn(provider: F) -> Self

Equivelant to calling Cached::new with a provider wrapped in a provider_fn type hint

Trait Implementations

impl<'cx, S, P> Default for Cached<'cx, S, P>where
    S: Service,
    P: Provider<'cx, S> + Default,

fn default() -> Self

Returns the “default value” for a type.

impl<'cx, S, P> Provider<'cx, &'static S> for Cached<'cx, S, P>where
    S: Service,
    P: Provider<'cx, S>,

fn provide(&'cx self, cx: &'cx Context<'_>) -> &'cx S::Output<'cx>

Build the output object
