Trait gotham::router::request::path::PathExtractor

pub trait PathExtractor: StaticResponseExtender {
    fn extract(
        state: &mut State, 
        segment_mapping: SegmentMapping
    ) -> Result<(), String>;
}

Extracts the Request path into State. On failure is capable of extending Response to indicate why the extraction process failed.

This functionality can be simply derived for application structs via PathExtractor, which will attempt to populate the associated struct. Combine with the derive StaticResponseExtender to have invalid query string data result in "400 Bad Request".

Custom responses can be created by using the PathExtractor derive and then implementing StaticResponseExtender independently.

Required Methods

fn extract(
    state: &mut State,
    segment_mapping: SegmentMapping
) -> Result<(), String>

Populates the struct with data from the Request path and adds it to State
