Struct DelayLayer 

pub struct DelayLayer { /* private fields */ }

Available on crate feature tower-delay only.

A Tower Layer that introduces a fixed delay before each request.

Implementations

impl DelayLayer

pub const fn new(delay: Duration) -> Self

Create a new DelayLayer with the given delay duration.

pub fn when<P, Req>(self, predicate: P) -> DelayLayerWith<P>

where P: Fn(&Req) -> bool + Clone,

Apply delay only to requests that satisfy a predicate.

Requests that don’t match the predicate will pass through without delay.

Example

use std::time::Duration;
use http::Request;
use hpx_util::tower::delay::DelayLayer;

// Only delay POST requests
let layer = DelayLayer::new(Duration::from_secs(1))
    .when(|req: &Request<_>| req.method() == http::Method::POST);
