pub fn round(self) -> Size2D<T, U>

where T: Round,

Rounds each component to the nearest integer value.

This behavior is preserved for negative values (unlike the basic cast).

enum Mm {}

assert_eq!(size2::<_, Mm>(-0.1, -0.8).round(), size2::<_, Mm>(0.0, -1.0))

pub fn ceil(self) -> Size2D<T, U>

where T: Ceil,

assert_eq!(size2::<_, Mm>(-0.1, -0.8).ceil(), size2::<_, Mm>(0.0, 0.0))

pub fn floor(self) -> Size2D<T, U>

where T: Floor,

Rounds each component to the biggest integer equal or lower than the original value.

Example

use euclid::size2;
use euclid::default::Size2D;

let from: Size2D<_> = size2(0.0, 10.0);
let to:  Size2D<_> = size2(8.0, -4.0);

assert_eq!(from.lerp(to, -1.0), size2(-8.0,  24.0));
assert_eq!(from.lerp(to,  0.0), size2( 0.0,  10.0));
assert_eq!(from.lerp(to,  0.5), size2( 4.0,   3.0));

where T: NumCast + Copy,

pub fn cast<NewT>(self) -> Size2D<NewT, U>

where NewT: NumCast,

Cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

where NewT: NumCast,

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

pub fn to_usize(self) -> Size2D<usize, U>

When casting from floating point sizes, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_u32(self) -> Size2D<u32, U>

Cast into an u32 size, truncating decimals if any.
