Struct geometry::point::Point

pub struct Point {
    pub x: i64,
    pub y: i64,
}

A point in two-dimensional space.

Fields

x: i64

The x-coordinate of the point.

y: i64

The y-coordinate of the point.

Implementations

impl Point

pub const fn new(x: i64, y: i64) -> Self

Creates a new Point from (x,y) coordinates.

pub const fn from_dir_coords(dir: Dir, a: i64, b: i64) -> Self

Creates a new point from the given direction and coordinates.

If dir is Dir::Horiz, a becomes the x-coordinate and b becomes the y-coordinate. If dir is Dir::Vert, a becomes the y-coordinate and b becomes the x-coordinate.

pub const fn zero() -> Self

Returns the origin, (0, 0).

Example

let origin = Point::zero();
assert_eq!(origin, Point::new(0, 0));

pub const fn coord(&self, dir: Dir) -> i64

Gets the coordinate associated with direction dir.

pub fn snap_to_grid(&self, grid: i64) -> Self

Snaps the x and y coordinates of this point to the nearest multiple of grid.

pub fn snap_x_to_grid(&self, grid: i64) -> Self

Snaps only the x-coordinate of this point to the nearest multiple of grid.

pub fn snap_y_to_grid(&self, grid: i64) -> Self
