Trait async_session_types::Repr

pub trait Repr<T>: Send + Sync + 'static where
    Self: Sized, {
    fn from(v: T) -> Self;
    fn try_into(self) -> Result<T, Self>;
    fn can_into(&self) -> bool;
}

Define for the wire representation, so that the raw messages can be lifted into it, and later the representation can be cast back into the expected types.

Similar to From<T> for R plus TryInto<T> for R. Unfortunately the built-in implementations lead to conflicts for DynMessage.

use async_session_types::*;

let repr: DynMessage = Repr::from(123u8);
let msg: u8 = Repr::try_into(repr).unwrap();

Required methods

fn from(v: T) -> Self

Convert a raw type to the common representation.

fn try_into(self) -> Result<T, Self>

Try to convert the representation back into one of the raw message types.

fn can_into(&self) -> bool

Check whether the representation can be turned into this raw type, without consuming.

Implementors

impl<T: 'static + Send + Sync> Repr<T> for DynMessage

We can turn anything into a DynMessage.
