Trait Returnval 

pub trait Returnval {
    type Sender<T>;
    type Receiver<T>;
    type SendError;
    type RecvResult<T>;

    // Required methods
    fn create<T>() -> (Self::Sender<T>, Self::Receiver<T>);
    fn send<T>(tx: Self::Sender<T>, msg: T) -> Result<(), Self::SendError>;
    fn recv<T>(rx: Self::Receiver<T>) -> Self::RecvResult<T>;
}

Required Associated Types

type Sender<T>

type Receiver<T>

type SendError

type RecvResult<T>

Required Methods

fn create<T>() -> (Self::Sender<T>, Self::Receiver<T>)

fn send<T>(tx: Self::Sender<T>, msg: T) -> Result<(), Self::SendError>

fn recv<T>(rx: Self::Receiver<T>) -> Self::RecvResult<T>

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.
