Function imageproc::drawing::draw_line_segment_mut

pub fn draw_line_segment_mut<I>(image: &mut I,
                                start: (f32, f32),
                                end: (f32, f32),

Draws as much of the line segment between start and end as lies inside the image bounds. Uses Bresenham's line drawing algorithm.
