Trait Get

pub trait Get<T> {
    // Required method
    fn get() -> T;
}

A trait for querying a single value from a type.

It is not required that the value is constant.

Required Methods

fn get() -> T

Return the current value.

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.
