Trait Implementations

impl Add for Point

type Output = Point

The resulting type after applying the + operator.

fn add(self, rhs: Point) -> Point

Performs the + operation.

impl AsMut<SDL_Point> for Point

fn as_mut(&mut self) -> &mut SDL_Point

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<SDL_Point> for Point

fn as_ref(&self) -> &SDL_Point

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Point

fn clone(&self) -> Point

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Point

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Deref for Point

fn deref(&self) -> &SDL_Point

Example

use sdl2::rect::Point;
let point = Point::new(2, 3);
assert_eq!(2, point.x);

type Target = SDL_Point

The resulting type after dereferencing.

impl DerefMut for Point

fn deref_mut(&mut self) -> &mut SDL_Point

Example

use sdl2::rect::Point;
let mut point = Point::new(2, 3);
point.x = 4;
assert_eq!(4, point.x);

impl Div<i32> for Point

type Output = Point

The resulting type after applying the / operator.

fn div(self, rhs: i32) -> Point

Performs the / operation.

impl From<(i32, i32)> for Point

fn from(_: (i32, i32)) -> Point

Converts to this type from the input type.

impl From<SDL_Point> for Point

fn from(prim: SDL_Point) -> Point

Converts to this type from the input type.

impl Into<(i32, i32)> for Point

fn into(self) -> (i32, i32)

Converts this type into the (usually inferred) input type.

impl Into<SDL_Point> for Point

fn into(self) -> SDL_Point

impl PartialEq for Point

fn eq(&self, other: &Point) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
