Expand description

Types that can be created from requests.

Extractors that implement FromRequest can consume the request body and can thus only be run once for handlers.

If your extractor owns only the request body and merely borrows the request parts, also implement FromRequestBody to compose with a preceding FromOwnedRequestParts extractor. If it doesn’t need to consume the request body at all, implement FromPartsStateRefPair instead.

Required Associated Types§

type Rejection

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

Required Methods§

fn from_request( req: Request, ) -> impl Future<Output = Result<Self, Self::Rejection>> + Send

Perform the extraction.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
