pub trait Lookup<I, T>: LutType<T> {
    // Required method
    fn lookup(table: &Self::Table, index: I) -> &T;
}

Required Methods

fn lookup(table: &Self::Table, index: I) -> &T

Get the value at an index.

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.
