[−][src]Crate ff_zeroize

This crate provides traits for working with finite fields.

LegendreSymbol
PrimeFieldDecodingError	An error that may occur when trying to interpret a `PrimeFieldRepr` as a `PrimeField` element.

Traits

Field	This trait represents an element of a field.
PrimeField	This represents an element of a prime field.
PrimeFieldRepr	This trait represents a wrapper around a biginteger which can encode any element of a particular prime field. It is a smart wrapper around a sequence of `u64` limbs, least-significant digit first.
ScalarEngine	An "engine" is a collection of types (fields, elliptic curve groups, etc.) with well-defined relationships. Specific relationships (for example, a pairing-friendly curve) can be defined in a subtrait.
SqrtField	This trait represents an element of a field that has a square root operation described for it.

adc	Calculate a + b + carry, returning the sum and modifying the carry value.
mac_with_carry	Calculate a + (b * c) + carry, returning the least significant digit and setting carry to the most significant digit.
sbb	Calculate a - b - borrow, returning the result and modifying the borrow value.
