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.
