Source 
pub trait Value:

}
Expand description

Values must be cloneable because a single value will be cloned to the respective multiple callers if some callers request by the same key.

Required Associated Types§

Source

type Key: Ord + Clone + Send + 'static

Key is used to route the values to the caller.

Required Methods§

Source

fn key(&self) -> &Self::Key

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.
