Struct ark_api::storage::LazyGetHandle

pub struct LazyGetHandle { /* private fields */ }

Handle to a lazy get request for AsyncStores.

Can be consumed as a Future or manually with the is_ready and take methods.

Implementations

impl LazyGetHandle

pub fn is_ready(&mut self) -> bool

Checks if the request is done or not.

Polls in the background, if necessary.

pub fn take(self) -> Option<Vec<u8>>

Consumes the handle and returns the underlying get result.

Panics

This will panic if is_ready() hasn’t returned true yet.

Trait Implementations

impl Future for LazyGetHandle

type Output = Option<Vec<u8, Global>>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
