Struct Position 

#[repr(C)]
pub struct Position {
    pub x: f32,
    pub y: f32,
}

The x and y position of any structure.

You can add and subtract Positions’s to and from each other

use agape_core::Position;

let mut position = Position::new(200.0,200.0);
position -= Position::unit(50.0);
assert_eq!(position.x,150.0);

position += Position::unit(120.0);
assert_eq!(position.y,270.0);

You can also add and subtract arbitrary floats to and from Position’s

use agape_core::Position;

let mut position = Position::new(200.0,200.0);
position += 55.0;
assert_eq!(position.x,255.0);

position -= 25.0;
assert_eq!(position.y,230.0);

Fields

x: f32

y: f32

Implementations

impl Position

pub fn new(x: f32, y: f32) -> Position

pub fn translate(&mut self, x: f32, y: f32)

Translate the position by x and y amount.

Example

use agape_core::Position;

let mut position = Position::new(0.0,0.0);
position.translate(40.0,100.0);

assert_eq!(Position::new(40.0,100.0),position);

pub fn set(&mut self, x: f32, y: f32)

Set the position

pub fn unit(value: f32) -> Position

Creates a Position where both the x and y are a single value.

Example

use agape_core::Position;

let position = Position::unit(500.0);

assert_eq!(position.x,position.y);
assert_eq!(position.x,500.0);

Trait Implementations

impl<I> AddAssign<I> for Position

where f32: AddAssign<I>, I: Copy,

fn add_assign(&mut self, rhs: I)

Performs the += operation.

impl AddAssign for Position

fn add_assign(&mut self, rhs: Position)

Performs the += operation.

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl Default for Position

fn default() -> Position

Returns the “default value” for a type.

impl From<PhysicalPosition<f64>> for Position

fn from(position: PhysicalPosition<f64>) -> Position

Converts to this type from the input type.

impl PartialEq for Position

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Position

fn partial_cmp(&self, other: &Position) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<I> SubAssign<I> for Position

where f32: SubAssign<I>, I: Copy,

fn sub_assign(&mut self, rhs: I)

Performs the -= operation.

impl SubAssign for Position

fn sub_assign(&mut self, rhs: Position)

Performs the -= operation.

impl Zeroable for Position

fn zeroed() -> Self

Calls zeroed.

impl Copy for Position

impl Pod for Position

impl StructuralPartialEq for Position
