[−][src]Struct async_compat::Compat
Compatibility adapter for futures and I/O types.
Implementations
impl<T> Compat<T>
[src]
pub fn new(t: T) -> Compat<T>ⓘ
[src]
Applies the compatibility adapter to a future or an I/O type.
Examples
Apply it to a future:
use async_compat::Compat; use std::time::Duration; use tokio::time::delay_for; futures::executor::block_on(Compat::new(async { // We can use tokio's timers because we're inside tokio context. tokio::time::delay_for(Duration::from_secs(1)).await; }));
Apply it to an I/O type:
use async_compat::{Compat, CompatExt}; use futures::prelude::*; futures::executor::block_on(Compat::new(async { // The `write_all` method comes from `futures::io::AsyncWriteExt`. Compat::new(tokio::io::stdout()).write_all(b"hello\n").await?; Ok(()) }))
pub fn into_inner(self) -> T
[src]
Unwraps the compatibility adapter.
Examples
use async_compat::Compat; let stdout = Compat::new(tokio::io::stdout()); let original = stdout.into_inner();
