Struct CacheLayer 

Source 
pub struct CacheLayer<'a, P, R> { /* private fields */ }
Expand description

Layer that adds cache to a tower::Service

This works by using a cache provider service that takes a ProviderRequest and returns a ProviderResponse.

Implementations§

Source§

impl<'a, P, R> CacheLayer<'a, P, R>

Source

pub fn new(provider: P) -> Self

Create a new CacheLayer

Trait Implementations§

Source§

fn layer(&self, inner: S) -> Self::Service
