Module ops

Available on crate feature arithmetic only.

Traits for arithmetic operations on elliptic curve field elements.

Traits

Add

The addition operator +.

AddAssign

The addition assignment operator +=.

BatchInvert

Perform a batched inversion on a sequence of field elements (i.e. base field elements or scalars) at an amortized cost that should be practically as efficient as a single inversion.

Invert

Perform an inversion on a field element (i.e. base field element or scalar)

LinearCombination

Linear combination.

LinearCombinationExt

Linear combination (extended version).

Mul

The multiplication operator *.

MulByGenerator

Multiplication by the generator.

Neg

The unary negation operator -.

Reduce

Modular reduction.

ReduceNonZero

Modular reduction to a non-zero output.

Shr

The right shift operator >>. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for _ >> _, setting the result type for integer operations to the type of the left-hand-side operand. This means that though a >> b and a.shr(b) are one and the same from an evaluation standpoint, they are different when it comes to type inference.

ShrAssign

The right shift assignment operator >>=.

Sub

The subtraction operator -.

SubAssign

The subtraction assignment operator -=.
