Struct gemini_engine::elements::geometry::Rect

pub struct Rect {
    pub pos: Vec2D,
    pub size: Vec2D,
    pub fill_char: ColChar,
    /* private fields */
}

The Rect takes a position and size, and returns a rectangle at that position with the given width and size when blit to a [View]

Fields

pos: Vec2D

size: Vec2D

fill_char: ColChar

Implementations

impl Rect

pub fn new(pos: Vec2D, size: Vec2D, fill_char: ColChar) -> Self

Trait Implementations

impl ViewElement for Rect

fn active_pixels(&self) -> Vec<Point>

Return a vector of every coordinate where a pixel should be placed and its respective ColChar. If your whole object is a solid colour, consider using utils::points_to_pixels() which will add the same ColChar to every point and can then be used as this function’s output
