Trait FromRequest 

pub trait FromRequest<Task>: Sized {
    type Error;

    // Required method
    fn from_request(
        req: &Task,
    ) -> impl Future<Output = Result<Self, Self::Error>> + Send;
}

A trait for extracting types from a task’s context.

Required Associated Types

type Error

The error type that can occur during extraction.

Required Methods

fn from_request( req: &Task, ) -> impl Future<Output = Result<Self, Self::Error>> + Send

Perform the extraction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
