Trait TwoWay 

pub trait TwoWay: OneWay {
    // Required method
    fn other_way(
        src: <Self as OneWay>::Dest,
    ) -> Result<<Self as OneWay>::Source>;
}

A trait for 2-way conversions that may fail.

Of course, for any x: Source, it should be the case that other_way(one_way(x)?)? == x when possible, but this is not required.

Required Methods

fn other_way(src: <Self as OneWay>::Dest) -> Result<<Self as OneWay>::Source>

Conversion from Dest to Source that may fail.

Dyn Compatibility

This trait is not dyn compatible.

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