[−][src]Trait hreq::server::Handler

pub trait Handler: Send + Sync + 'static {
    fn call<'a>(
        &'a self, 
        req: Request<Body>
    ) -> Pin<Box<dyn Future<Output = Reply> + Send + 'a>>;
}

Trait for a request handler that doesn't use a state.

Typically this trait is not used directly since there is a blanket implementation for any function that matches this signature:

ⓘThis example is not tested
async fn my_handler(req: Request<Body>) -> impl Into<Reply> {
   ...
}

Reply is not a type you would use in your own type signatures. impl Into<Reply> represents a whole range of (concrete) possible return types. See Reply for more details.

Examples

use hreq::prelude::*;

async fn start_server() {
   let mut server = Server::new();

   server.at("/hello/:name").get(hello_there);

   server.listen(3000).await.unwrap();
}

async fn hello_there(req: http::Request<Body>) -> String {
   format!("Hello {}", req.path_param("name").unwrap())
}

Required methods

fn call<'a>(
    &'a self,
    req: Request<Body>
) -> Pin<Box<dyn Future<Output = Reply> + Send + 'a>>
