Crate async_trait_proto
source · [−]Expand description
Async trait prototype using the desugarization described in RFC 3185 Static Async Fn in Traits.
It should be faster than async-trait because it doesn’t use allocations on every invocation and type erasure.
Requires these feature flags and a nightly compiler:
#![feature(generic_associated_types)]#![feature(type_alias_impl_trait)]
Example
#![feature(generic_associated_types)]
#![feature(type_alias_impl_trait)]
use async_trait_proto::async_trait_proto;
struct Foo;
#[async_trait_proto]
trait Bar {
async fn wait(&self);
}
#[async_trait_proto]
impl Bar for Foo {
async fn wait(&self) {
sleep(Duration::from_secs(10)).await;
}
}
