Trait FromRequestContextRefPair

pub trait FromRequestContextRefPair<S>:
    Sized
    + Send
    + Sync
    + 'static {
    type Rejection: IntoResponse;

    // Required method
    fn from_request_context_ref_pair(
        ctx: &Context<S>,
        parts: &Parts,
    ) -> impl Future<Output = Result<Self, Self::Rejection>> + Send;
}

Types that can be created from request parts.

Extractors that implement FromRequestParts cannot consume the request body and can thus be run in any order for handlers.

If your extractor needs to consume the request body then you should implement FromRequest and not [FromRequestParts].

Required Associated Types

type Rejection: IntoResponse

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_context_ref_pair( ctx: &Context<S>, parts: &Parts, ) -> impl Future<Output = Result<Self, Self::Rejection>> + Send

Perform the extraction.
