Trait FromKey 

pub trait FromKey: Sized {
    // Required method
    fn from_key(value: Key) -> Result<Self, Error>;
}

A trait used to convert Key values to various types.

See the convert documentation for more information.

Required Methods

fn from_key(value: Key) -> Result<Self, Error>

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.
