Traits

Angle	Angles and their associated trigonometric functions.
Array	An array containing elements of type Element
AsPrimitive	A generic interface for casting between machine scalars with the as operator, which admits narrowing and precision loss. Implementers of this trait AsPrimitive should behave like a primitive numeric type (e.g. a newtype around another primitive), and the intended conversion must never fail.
Bounded	Numbers which have upper and lower bounds
CheckedAdd	Performs addition that returns None instead of wrapping around on overflow.
CheckedDiv	Performs division that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedMul	Performs multiplication that returns None instead of wrapping around on underflow or overflow.
CheckedNeg	Performs negation that returns None if the result can’t be represented.
CheckedRem	Performs an integral remainder that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedShl	Performs a left shift that returns None on shifts larger than the type width.
CheckedShr	Performs a right shift that returns None on shifts larger than the type width.
CheckedSub	Performs subtraction that returns None instead of wrapping around on underflow.
DeviceExt	Utility methods not meant to be in the main API.
ElementWise	Element-wise arithmetic operations. These are supplied for pragmatic reasons, but will usually fall outside of traditional algebraic properties.
EuclideanSpace	Points in a Euclidean space with an associated space of displacement vectors.
Float	Generic trait for floating point numbers
FloatConst
FromPrimitive	A generic trait for converting a number to a value.
InnerSpace	Vectors that also have a dot (or inner) product.
Inv	Unary operator for retrieving the multiplicative inverse, or reciprocal, of a value.
Matrix	A column-major matrix of arbitrary dimensions.
MetricSpace	A type with a distance function between values.
MulAdd	Fused multiply-add. Computes (self * a) + b with only one rounding error, yielding a more accurate result than an unfused multiply-add.
MulAddAssign	The fused multiply-add assignment operation.
Num	The base trait for numeric types, covering 0 and 1 values, comparisons, basic numeric operations, and string conversion.
NumAssign	The trait for Num types which also implement assignment operators.
NumAssignOps	The trait for types implementing numeric assignment operators (like +=).
NumAssignRef	The trait for NumAssign types which also implement assignment operations taking the second operand by reference.
NumCast	An interface for casting between machine scalars.
NumOps	The trait for types implementing basic numeric operations
NumRef	The trait for Num types which also implement numeric operations taking the second operand by reference.
One	Defines a multiplicative identity element for Self.
Pow	Binary operator for raising a value to a power.
PrimInt	Generic trait for primitive integers.
RefNum	The trait for references which implement numeric operations, taking the second operand either by value or by reference.
Rotation	A trait for a generic rotation. A rotation is a transformation that creates a circular motion, and preserves at least one point in the space.
Rotation2	A two-dimensional rotation.
Rotation3	A three-dimensional rotation.
Saturating	Saturating math operations. Deprecated, use SaturatingAdd, SaturatingSub and SaturatingMul instead.
SaturatingAdd	Performs addition that saturates at the numeric bounds instead of overflowing.
SaturatingMul	Performs multiplication that saturates at the numeric bounds instead of overflowing.
SaturatingSub	Performs subtraction that saturates at the numeric bounds instead of overflowing.
Signed	Useful functions for signed numbers (i.e. numbers that can be negative).
SquareMatrix	A column-major major matrix where the rows and column vectors are of the same dimensions.
ToPrimitive	A generic trait for converting a value to a number.
Transform	A trait representing an affine transformation that can be applied to points or vectors. An affine transformation is one which
Transform2
Transform3
Unsigned	A trait for values which cannot be negative
VectorSpace	Vectors that can be added together and multiplied by scalars.
WrappingAdd	Performs addition that wraps around on overflow.
WrappingMul	Performs multiplication that wraps around on overflow.
WrappingNeg	Performs a negation that does not panic.
WrappingShl	Performs a left shift that does not panic.
WrappingShr	Performs a right shift that does not panic.
WrappingSub	Performs subtraction that wraps around on overflow.
Zero	Defines an additive identity element for Self.

Functions

abs	Computes the absolute value.
abs_sub	The positive difference of two numbers.
cast	Cast from one machine scalar to another.
checked_pow	Raises a value to the power of exp, returning None if an overflow occurred.
clamp	A value bounded by a minimum and a maximum
clamp_max	A value bounded by a maximum value
clamp_min	A value bounded by a minimum value
from_str	Get a SVG/CSS3 color by name. Can be toggled with the "named_from_str" Cargo feature.
one	Returns the multiplicative identity, 1.
pow	Raises a value to the power of exp, using exponentiation by squaring.
random	Generates a random value using the thread-local random number generator.
signum	Returns the sign of the number.
zero	Returns the additive identity, 0.

Type Definitions

Hsla	Linear HSL with an alpha component. See the Hsla implementation in Alpha.
Hsva	Linear HSV with an alpha component. See the Hsva implementation in Alpha.
LinSrgb	Linear sRGB.
LinSrgba	Linear sRGB with an alpha component.
Srgb	Nonlinear sRGB.
Srgba	Nonlinear sRGB with an alpha component.
