Trait Protocol

pub trait Protocol<'resp>: Sealed {
    type HandleMailReturnType;

    const PROTOCOL: ProtocolName;

    // Required method
    fn handle_mail_return_type_as_stream(
        _resp: Self::HandleMailReturnType,
    ) -> Pin<Box<dyn Stream<Item = Decision<()>> + Send + 'resp>>;
}

Required Associated Constants

const PROTOCOL: ProtocolName

Required Associated Types

type HandleMailReturnType

Required Methods

fn handle_mail_return_type_as_stream( _resp: Self::HandleMailReturnType, ) -> Pin<Box<dyn Stream<Item = Decision<()>> + Send + 'resp>>

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.
