Struct warp::reject::Rejection

source · 
pub struct Rejection { /* private fields */ }
Expand description

Rejection of a request by a Filter.

See the reject documentation for more.

Implementations§

source§

impl Rejection

source

pub fn find<T: 'static>(&self) -> Option<&T>

Searches this Rejection for a specific cause.

A Rejection will accumulate causes over a Filter chain. This method can search through them and return the first cause of this type.

Example
#[derive(Debug)]
struct Nope;

impl warp::reject::Reject for Nope {}

let reject = warp::reject::custom(Nope);

if let Some(nope) = reject.find::<Nope>() {
   println!("found it: {:?}", nope);
}
source

pub fn is_not_found(&self) -> bool

Returns true if this Rejection was made via warp::reject::not_found.

Example
let rejection = warp::reject();

assert!(rejection.is_not_found());
