met, otherwise the behavior is undefined.

.
pub fn length(self) -> f64
[src]

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

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

See also Self::try_normalize
and Self::normalize_or_zero
.

[src]
Returns self
normalized to length 1.0 if possible, else returns None
.
In particular, if the input is zero (or very close to zero), or non-finite,
the result of this operation will be None
.
See also Self::normalize_or_zero
.
pub fn normalize_or_zero(self) -> Self
[src]
Returns self
normalized to length 1.0 if possible, else returns zero.

See also Self::try_normalize
.
pub fn is_normalized(self) -> bool

Returns whether self
is length 1.0
or not.
Uses a precision threshold of 1e-6

pub fn lerp(self, other: Self, s: f64) -> Self
[src]
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 abs_diff_eq(self, other: Self, max_abs_diff: f64) -> bool
[src]
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 vectors 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.
For more see comparing floating point numbers.
pub fn clamp_length(self, min: f64, max: f64) -> Self
[src]
Returns a vector with a length no less than min
and no more than max

[src]
Returns a vector with a length no less than min
pub fn angle_between(self, other: Self) -> f64
[src]
Returns the angle (in radians) between self
and other
.
The input vectors do not need to be unit length however they must be non-zero.

Casts all elements of self
to f32
.
pub fn as_i32(&self) -> IVec2
[src]
