Macro actix_service::always_ready
source · macro_rules! always_ready {
() => { ... };
}
Expand description
An implementation of poll_ready
that always signals readiness.
This should only be used for basic leaf services that have no concept of un-readiness.
For wrapper or other service types, use [forward_ready!
] for simple cases or write a bespoke
poll_ready
implementation.
§Examples
use actix_service::Service;
use futures_util::future::{ready, Ready};
struct IdentityService;
impl Service<u32> for IdentityService {
type Response = u32;
type Error = ();
type Future = Ready<Result<Self::Response, Self::Error>>;
actix_service::always_ready!();
fn call(&self, req: u32) -> Self::Future {
ready(Ok(req))
}
}
