Enum solana_jsonrpc_tcp_server::tokio::prelude::Async

pub enum Async<T> {
    Ready(T),
    NotReady,
}

Return type of future, indicating whether a value is ready or not.

Variants

Ready(T)

Represents that a value is immediately ready.

NotReady

Represents that a value is not ready yet, but may be so later.

Methods

impl<T> Async<T>

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

Change the success value of this Async with the closure provided

pub fn is_ready(&self) -> bool

Returns whether this is Async::Ready

pub fn is_not_ready(&self) -> bool
