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", so this trait is not object safe.
