Module gotham::extractor

Extracts request data into type-safe structs using Serde.

Extractors are added to route definitions when defining a Router. The PathExtractor and QueryStringExtractor traits provide usage examples.

The request data is extracted by the Route implementation when dispatching the request. The application-provided data structure which implements the extractor trait is used to deserialize the data and store it within the request State before the request is dispatched to the Handler.

Structs

NoopPathExtractor	A PathExtractor that does not extract/store any data from the Request path.
NoopQueryStringExtractor	A QueryStringExtractor that does not extract/store any data.

Traits

PathExtractor	Defines a binding for storing the dynamic segments of the Request path in State. On failure the StaticResponseExtender implementation extends the Response to indicate why the extraction process failed.
QueryStringExtractor	Defines a binding for storing the query parameters from the Request URI in State. On failure the StaticResponseExtender implementation extends the Response to indicate why the extraction process failed.
