Struct routerify::PreMiddleware[−][src]

pub struct PreMiddleware<E> { /* fields omitted */ }

Expand description

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>

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,

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();
