Trait CharSet

pub trait CharSet {
    const SIZE: usize;

    // Required methods
    fn map(ch: char) -> usize;
    fn unmap(hash: usize) -> char;
}

Implement this trait to space optimize your trie according to your character set

Required Associated Constants

const SIZE: usize

number of characters in the CharSet

Required Methods

fn map(ch: char) -> usize

provide one to one mapping from char to usize

fn unmap(hash: usize) -> char

provide one to one mapping from usize to char

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.

Implementors

impl CharSet for Ascii

const SIZE: usize = 256usize

impl CharSet for LowerCase

const SIZE: usize = 26usize

impl CharSet for UpperCase

const SIZE: usize = 26usize
