ReqwestUpstream

Struct ReqwestUpstream 

Source
pub struct ReqwestUpstream<'a> { /* private fields */ }
Expand description

Upstream wrapper that bridges reqwest-middleware’s Next to hitbox’s Upstream trait.

This adapter allows the hitbox cache FSM to call the remaining middleware chain when it needs to fetch fresh data from upstream.

§Type Parameter

The lifetime 'a comes from Next<'a>, representing the middleware chain’s lifetime. This is why DisabledOffload is used in the middleware - we cannot spawn background tasks with non-'static lifetimes.

Implementations§

Source§

impl<'a> ReqwestUpstream<'a>

Source

pub fn new(next: Next<'a>, extensions: Extensions) -> Self

Creates a new upstream wrapper. Typically called internally by CacheMiddleware.

Trait Implementations§

Source§

impl<'a> Upstream<CacheableHttpRequest<Body>> for ReqwestUpstream<'a>

Implementation of Upstream for reqwest-middleware integration.

This allows the hitbox cache FSM to treat the remaining middleware chain as an upstream service that can be called on cache misses.

Source§

type Response = Result<CacheableHttpResponse<Body>, Error>

The response type returned by the upstream service
Source§

type Future = Pin<Box<dyn Future<Output = <ReqwestUpstream<'a> as Upstream<CacheableHttpRequest<Body>>>::Response> + Send + 'a>>

The future that resolves to the response
Source§

fn call(&mut self, req: CacheableHttpRequest<Body>) -> Self::Future

Call the upstream service with the given request
