Trait Implementations

impl<W: WebRequest, F, T> WebRequest for MapErr<W, F, T>

where F: FnMut(W::Error) -> T,

type Error = T

The error generated from access of malformed or invalid requests.

type Response = MapErr<<W as WebRequest>::Response, F, T>

The corresponding type of Responses returned from this module.

fn query( &mut self, ) -> Result<Cow<'_, dyn QueryParameter + 'static>, Self::Error>

Retrieve a parsed version of the url query.

fn urlbody( &mut self, ) -> Result<Cow<'_, dyn QueryParameter + 'static>, Self::Error>
