Struct euclid::size::Size2D[][src]

#[repr(C)]
pub struct Size2D<T, U> { pub width: T, pub height: T, // some fields omitted }
Expand description

A 2d size tagged with a unit.

Fields

width: T

The extent of the element in the U units along the x axis (usually horizontal).

height: T

The extent of the element in the U units along the y axis (usually vertical).

Implementations

The same as Zero::zero() but available without importing trait.

Constructor taking scalar values.

Constructor taking scalar strongly typed lengths.

Tag a unitless value with units.

Return this size as an array of two elements (width, then height).

Return this size as a tuple of two elements (width, then height).

Return this size as a vector with width and height.

Drop the units, preserving only the numeric value.

Cast the unit

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))

Rounds each component to the smallest integer equal or greater than the original value.

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

enum Mm {}

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

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

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

enum Mm {}

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

Returns result of multiplication of both components

Linearly interpolate each component between this size and another size.

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));
assert_eq!(from.lerp(to,  1.0), size2( 8.0,  -4.0));
assert_eq!(from.lerp(to,  2.0), size2(16.0, -18.0));

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.

Fallible 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.

Cast into an f32 size.

Cast into an f64 size.

Cast into an uint size, truncating decimals if any.

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.

Cast into an u32 size, truncating decimals if any.

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.

Cast into an u64 size, truncating decimals if any.

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.

Cast into an i32 size, truncating decimals if any.

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.

Cast into an i64 size, truncating decimals if any.

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.

Computes the absolute value of each component.

For f32 and f64, NaN will be returned for component if the component is NaN.

For signed integers, ::MIN will be returned for component if the component is ::MIN.

Returns true if both components is positive and false any component is zero or negative.

Returns the size each component of which are minimum of this size and another.

Returns the size each component of which are maximum of this size and another.

Returns the size each component of which clamped by corresponding components of start and end.

Shortcut for self.max(start).min(end).

Returns vector with results of “greater then” operation on each component.

Returns vector with results of “lower then” operation on each component.

Returns true if any component of size is zero or negative.

Returns vector with results of “equal” operation on each component.

Returns vector with results of “not equal” operation on each component.
