Describes the functionality required for interfacing with HTTP client middleware

Required methods

fn is_method_get_head(&self) -> bool

Determines if the request method is either GET or HEAD

fn policy(&self, response: &HttpResponse) -> Result<CachePolicy>

Returns a new cache policy with default options

fn policy_with_options(
    &self,
    response: &HttpResponse,
    options: CacheOptions
) -> Result<CachePolicy>

Returns a new cache policy with custom options

fn update_headers(&mut self, parts: Parts) -> Result<()>

Attempts to update the request headers with the passed http::request::Parts

fn set_no_cache(&mut self) -> Result<()>

Attempts to force the “no-cache” directive on the request

fn parts(&self) -> Result<Parts>

Attempts to construct http::request::Parts from the request

fn url(&self) -> Result<&Url>

Attempts to determine the requested url

fn method(&self) -> Result<String>

Attempts to determine the request method

fn remote_fetch<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = Result<HttpResponse>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Attempts to fetch an upstream resource and return an HttpResponse
