Struct warp::filters::BoxedFilter

pub struct BoxedFilter<T: Tuple> {
    filter: Arc<dyn Filter<Extract = T, Error = Rejection, Future = Pin<Box<dyn Future<Output = Result<T, Rejection>> + Send>>> + Send + Sync>,
}

A type representing a boxed Filter trait object.

The filter inside is a dynamic trait object. The purpose of this type is to ease returning Filters from other functions.

To create one, call Filter::boxed on any filter.

Examples

use warp::{Filter, filters::BoxedFilter, Reply};

pub fn assets_filter() -> BoxedFilter<(impl Reply,)> {
    warp::path("assets")
        .and(warp::fs::dir("./assets"))
        .boxed()
}

Fields

filter: Arc<dyn Filter<Extract = T, Error = Rejection, Future = Pin<Box<dyn Future<Output = Result<T, Rejection>> + Send>>> + Send + Sync>
