Trait FromRequestHead 

pub trait FromRequestHead: Sized {
    // Required method
    fn from_request_head(
        head: &RequestHead,
    ) -> impl Future<Output = Result<Self>> + Send;
}

Trait for extractors that don’t consume the request body.

Extractors implementing this trait are used in route handlers that don’t consume the request and therefore can be used multiple times per request.

If you need to consume the body of the request, use FromRequest instead.

See crate::request::extractors documentation for more information about extractors.

Required Methods

fn from_request_head( head: &RequestHead, ) -> impl Future<Output = Result<Self>> + Send

Extracts data from the request head.

Errors

Throws an error if the extractor fails to extract the data from the request head.

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.
