pub trait FromRequest<S, M = ViaRequest>: Sized {
type Rejection: IntoResponse;
// Required method
fn from_request(
req: Request,
state: &S,
) -> impl Future<Output = Result<Self, Self::Rejection>> + Send;
}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 doesn’t need to consume the request body then you should implement
FromRequestParts and not FromRequest.
See axum::extract for more general docs about extractors.
Required Associated Types§
Sourcetype Rejection: IntoResponse
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§
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
