Trait FromRequest 

pub trait FromRequest<'a, M = ViaRequest>: Sized {
    type Error: ResponseError;

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

Required Associated Types

type Error: ResponseError

Required Methods

fn from_request( head: &'a mut Head, body: RequestBody, ) -> 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.
