Trait PrefValue 

pub trait PrefValue:
    Clone
    + PartialEq
    + 'static {
    // Required methods
    fn encode(&self) -> String;
    fn decode(s: &str) -> Option<Self>;
}

A value a Pref can hold: encoded to one string in the store and back. Implemented for the plain scalars and strings; enums get it from pref_enum!.

Required Methods

fn encode(&self) -> String

fn decode(s: &str) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

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