Struct tower::filter::Filter [−][src]
This is supported on crate feature
filter
only.Conditionally dispatch requests to the inner service based on a predicate.
Implementations
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]
pub fn check<R>(&mut self, request: R) -> Result<U::Request, BoxError> where
U: Predicate<R>,
[src]
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
