Trait FromRequestHead 

pub trait FromRequestHead<'a>: Sized {
    type Error: ResponseError;

    // Required method
    fn from_request_head(
        head: &'a mut Head,
    ) -> impl Future<Output = Result<Self, Self::Error>> + Send;
}

Required Associated Types

type Error: ResponseError

Required Methods

fn from_request_head( head: &'a mut Head, ) -> impl Future<Output = Result<Self, Self::Error>> + Send

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.
