Methods

impl Vec2

pub fn sign(self) -> Self

Returns a new Vec4 with elements representing the sign of self.

• 1.0 if the number is positive, +0.0 or INFINITY
• -1.0 if the number is negative, -0.0 or NEG_INFINITY

pub fn reciprocal(self) -> Self

Computes the reciprocal 1.0/n of each element, returning the results in a new Vec2.

pub fn lerp(self, other: Self, s: f32) -> Self

Performs a linear interpolation between self and other based on the value s.

When s is 0.0, the result will be equal to self. When s is 1.0, the result will be equal to other.

pub fn is_normalized(self) -> bool

Returns whether self is length 1.0 or not.

Uses a precision threshold of 1e-6.

pub fn abs_diff_eq(self, other: Self, max_abs_diff: f32) -> bool

Returns true if the absolute difference of all elements between self and other is less than or equal to max_abs_diff.

This can be used to compare if two Vec2's contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

Creates a new Vec2 with values [x: 0.0, y: 1.0].

pub fn splat(v: f32) -> Vec2

Creates a new Vec2 with all elements set to v.

Computes the dot product of self and other.

pub fn length(self) -> f32

Computes the length of self.

Computes the squared length of self.

This is generally faster than Vec2::length() as it avoids a square root operation.

Computes 1.0 / Vec2::length().

For valid results, self must not be of length zero.

Returns self normalized to length 1.0.

For valid results, self must not be of length zero.

In other words, this computes [x: min(x1, x2), y: min(y1, y2)], taking the minimum of each element individually.

Returns the vertical maximum of self and other.

In other words, this computes [x: max(x1, x2), y: max(y1, y2)], taking the maximum of each element individually.

pub fn min_element(self) -> f32

Returns the horizontal minimum of self's elements.

In other words, this computes min(x, y).

pub fn max_element(self) -> f32

Returns the horizontal maximum of self's elements.

In other words, this computes max(x, y).

pub fn cmpeq(self, other: Vec2) -> Vec2Mask

In other words, this computes [x1 == x2, y1 == y2, z1 == z2, w1 == w2].

pub fn cmpne(self, other: Vec2) -> Vec2Mask

Performs a vertical != comparison between self and other, returning a Vec2Mask of the results.

In other words, this computes [x1 != x2, y1 != y2, z1 != z2, w1 != w2].

pub fn cmple(self, other: Vec2) -> Vec2Mask

Performs a vertical <= comparison between self and other, returning a Vec2Mask of the results.

In other words, this computes [x1 <= x2, y1 <= y2, z1 <= z2, w1 <= w2].

pub fn cmplt(self, other: Vec2) -> Vec2Mask

Performs a vertical < comparison between self and other, returning a Vec2Mask of the results.

In other words, this computes [x1 < x2, y1 < y2, z1 < z2, w1 < w2].

Panics

Panics if slice is less than two elements long.

pub fn write_to_slice_unaligned(self, slice: &mut [f32])
