pub fn uniform_grid_spacer(
spacer: impl Fn(GridInput) -> [f64; 3] + 'static
) -> Box<dyn Fn(GridInput) -> Vec<GridMark>>Expand description
Splits the grid into uniform-sized spacings (e.g. 100, 25, 1).
This function should return 3 positive step sizes, designating where the lines in the grid are drawn. Lines are thicker for larger step sizes. Ordering of returned value is irrelevant.
Why only 3 step sizes? Three is the number of different line thicknesses that egui typically uses in the grid.
Ideally, those 3 are not hardcoded values, but depend on the visible range (accessible through GridInput).
