Function tower::util::service_fn [−][src]
pub fn service_fn<T>(f: T) -> ServiceFn<T>
This is supported on crate feature
util
only.Returns a new ServiceFn
with the given closure.
This lets you build a Service
from an async function that returns a Result
.
Example
use tower::{service_fn, Service, ServiceExt, BoxError}; async fn handle(request: Request) -> Result<Response, BoxError> { let response = Response::new("Hello, World!"); Ok(response) } let mut service = service_fn(handle); let response = service .ready_and() .await? .call(Request::new()) .await?; assert_eq!("Hello, World!", response.into_body());
