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§

source

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§

source

fn from_request<'life0, 'async_trait>( req: Request<Body>, state: &'life0 S ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Perform the extraction.

Object Safety§

This trait is not object safe.
