Interner

This crate provides a simple string interner through the Interner structure. This structure allows you to retrieve a unique Symbol to a &str.

Usage

use trunk_interner::{Interner, Symbol};

fn main() {
    let mut interner = Interner::default();

    let my_string_symbol: Symbol = interner.intern("Hello, world!");
    let my_original_string: &str = interner.get(my_string_symbol);
}

If a &str is interned multiple times, the same Symbol will be returned, in theory minimizing the amount of memory used by your program due to a reduced number of String allocations.
