Module gotham::extractor [−][src]
Expand description
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
A PathExtractor that does not extract/store any data from the Request path.
A QueryStringExtractor that does not extract/store any data.
Traits
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.
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.
