Struct comprez::Unsigned

pub struct Unsigned;

Determine if a char is a valid identifier for a parser and/or lexer according to Unicode Standard Annex #31 rules.

use comprez::Unsigned;

fn main() {
    let num = 1234u32;

    let compressed = Unsigned::compress_61_439(num).unwrap();
    let decompressed = Unsigned::decompress_61_439(compressed.to_vec()).unwrap();

    println!("size before compression: {}", num.to_be_bytes().len());
    //size before compression: 4

    println!("size after compression: {}", compressed.len());
    //size after compression: 2

    println!("{}", decompressed == num);
    //true
}

features

unicode-xid supports a no_std feature. This eliminates dependence on std, and instead uses equivalent functions from core.
