Struct routerify::PreMiddleware [−][src]
The pre middleware type. Refer to Pre Middleware for more info.
This PreMiddleware<E>
type accepts a single type parameter: E
.
- The
E
represents any error type which will be used by route handlers and the middlewares. This error type must implement the std::error::Error.
Implementations
impl<E: Into<Box<dyn Error + Send + Sync>> + 'static> PreMiddleware<E>
[src]
pub fn new<P, H, R>(path: P, handler: H) -> Result<PreMiddleware<E>> where
P: Into<String>,
H: Fn(Request<Body>) -> R + Send + Sync + 'static,
R: Future<Output = Result<Request<Body>, E>> + Send + 'static,
[src]
P: Into<String>,
H: Fn(Request<Body>) -> R + Send + Sync + 'static,
R: Future<Output = Result<Request<Body>, E>> + Send + 'static,
Creates a pre middleware with a handler at the specified path.
Examples
use routerify::{Router, Middleware, PreMiddleware}; use hyper::{Request, Body}; use std::convert::Infallible; let router = Router::builder() .middleware(Middleware::Pre(PreMiddleware::new("/abc", |req| async move { /* Do some operations */ Ok(req) }).unwrap())) .build() .unwrap();
