Trait CodedError 

pub trait CodedError: Error {
    // Required method
    fn code(&self) -> u64;
}

An application failure a request is answered with. The peer dispatches on the code and may show the message. Codes below 0x100 are the protocol’s schema::ReservedErrors, an application assigns its own from 0x100 up.

Implementing it converts the error into schema::Error, so a handler can fail a request with ? and super::Responder::fail takes it directly.

Required Methods

fn code(&self) -> u64

Code identifying the failure to the peer.

Dyn Compatibility

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