Unary operation kind

Variants

Neg

Negation: -a

Abs

Absolute value: |a|

Sign

Sign: returns -1 for negative, 0 for zero, 1 for positive

Sqrt

Square root: sqrt(a)

Rsqrt

Reciprocal square root: 1/sqrt(a) - critical for normalization layers

Square

Square: a^2

Cbrt

Cube root: cbrt(a)

Recip

Reciprocal: 1/a

Exp

Exponential: e^a

Exp2

Base-2 exponential: 2^a

Expm1

Exponential minus 1: e^a - 1 (numerically stable for small a)

Log

Natural log: ln(a)

Log2

Base-2 logarithm: log2(a)

Log10

Base-10 logarithm: log10(a)

Log1p

Natural log of 1+a: ln(1+a) (numerically stable for small a)

Sin

Sine: sin(a)

Cos

Cosine: cos(a)

Tan

Tangent: tan(a)

Asin

Arc sine (inverse sine): asin(a), domain [-1,1], range [-π/2, π/2]

Acos

Arc cosine (inverse cosine): acos(a), domain [-1,1], range [0, π]

Atan

Arc tangent (inverse tangent): atan(a)

Sinh

Hyperbolic sine: sinh(a)

Cosh

Hyperbolic cosine: cosh(a)

Tanh

Hyperbolic tangent: tanh(a)

Asinh

Inverse hyperbolic sine: asinh(a)

Acosh

Inverse hyperbolic cosine: acosh(a), domain [1, ∞)

Atanh

Inverse hyperbolic tangent: atanh(a), domain (-1, 1)

Floor

Floor: floor(a)

Ceil

Ceiling: ceil(a)

Round

Round to nearest: round(a)

Trunc

Truncate toward zero: trunc(a)

Trait Implementations

impl Clone for UnaryOp

fn clone(&self) -> UnaryOp

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnaryOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UnaryOp

fn eq(&self, other: &UnaryOp) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for UnaryOp

impl Eq for UnaryOp

impl StructuralPartialEq for UnaryOp
