Struct tower::filter::Filter[][src]

pub struct Filter<T, U> { /* fields omitted */ }
This is supported on crate feature filter only.

Conditionally dispatch requests to the inner service based on a predicate.


impl<T, U> Filter<T, U>[src]

pub fn new(inner: T, predicate: U) -> Self[src]

Returns a new Filter service wrapping inner.

pub fn layer(predicate: U) -> FilterLayer<U>[src]

Returns a new Layer that wraps services with a Filter service with the given Predicate.

pub fn check<R>(&mut self, request: R) -> Result<U::Request, BoxError> where
    U: Predicate<R>, 

Check a Request value against this filter’s predicate.

pub fn get_ref(&self) -> &T[src]

Get a reference to the inner service

pub fn get_mut(&mut self) -> &mut T[src]

Get a mutable reference to the inner service

pub fn into_inner(self) -> T[src]

Consume self, returning the inner service
