Trait Values 

pub trait Values {
    // Required method
    fn get_value(&self, key: &str) -> Option<Cow<'_, str>>;
}

Required Methods

fn get_value(&self, key: &str) -> Option<Cow<'_, str>>

Dyn Compatibility

This trait is dyn compatible.

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