Struct sqrid::Gridbool

pub struct Gridbool<const WIDTH: u16, const HEIGHT: u16, const WORDS: usize>(_);

Space-optimized grid of booleans using bitmaps

Gridbool uses an array of u32 to implement a Qa-indexable grid of booleans, balancing space and performance.

At the moment we need to provide the number of u32 WORDS to use due to rust generic const limitations. We are able to check that the value is appropriate, though.

We can use the gridbool_create macro to use a Qa as a source of these values.
