Enjoy the efficient char range! Also provided are ways of working with noncontinuous sets of unicode codepoints as well as mapping unicode codepoints to values.

• CharRange is a simple range of codepoints, effectively std::ops::RangeInclusive<char>.
• CharSet is a set of codepoints handled as a sorted vector of compact ranges.
• CharTrie is a static set of codepoints optimized for wide codepoint coverage.
• CharMap is a mapping from compact ranges of codepoints to values.

Features

• set: Adds the CharSet type.
• trie: Adds the CharTrie type.
• map: Adds the CharMap reference type.
• owned-set: Adds the CharSetBuf type.
• new-trie: Adds code generation support for CharTries.
• par-iter: Adds implementations of rayon::IntoParallelIterator.

Example

fn main() {
    use mileage::CharRange;
    for ch in CharRange::from('a'..='z') {
        // ch is each codepoint in lowercase ascii in sorted order
        dbg!(ch);
    }
    for ch in CharRange::from(..) {
        // ch is every valid char in sorted order
        dbg!(ch);
    }
}

Planned (eventually)

• CharMapRefMut
• CharMapBuf
