Trait StrLookup

pub trait StrLookup {
    type Key: Display;

    // Required methods
    fn insert(value: &str) -> Self::Key;
    fn get_str(key: &Self::Key) -> &str;
}

A trait for management of str associated with StringId.

It should make link between a key (Id of a StringId) and an associated str.

Required Associated Types

type Key: Display

Required Methods

fn insert(value: &str) -> Self::Key

Insert the str value into lookup data, and return a corresponding unique key.

fn get_str(key: &Self::Key) -> &str

Get the str corresponding do the 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.
