unicode-line-stacker 1.0.0

Tiny library for stacking Unicode line-drawing characters on top of each other.

Unicode Line Stacker

What is this crate?

Suppose you are drawing "lines" in the terminal using box-drawing characters and are filling in a 2-D grid of chars.

You might first put down a ┌ but then later want to draw a ┴ on top of that. This crate will calculate that the resulting char should be a ┼.

You can also convert a 4-bit bit string into a line drawing character.


let combo = unicode_line_stacker::stack('┌', '┴');
assert_eq!(Some('┼'), combo);

// Bit string format: for each of the four directions, clockwise starting from
// top (least significant to most significant), 1 means "on" and 0 means "off."
let c = unicode_line_stacker::bits_to_char(0b1011);
assert_eq!('┴', c);

Current Functionality

Right now the crate only supports the "light" line drawing characters in the four cardinal directions.
