Crate fff

This crate provides traits for working with finite fields.

Structs

• BitIterator
• CPU_SUPPORTS_ADX_INSTRUCTION

Enums

• 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.

Functions

• 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.
• mod_mul_4w_assign
• sbb
  Calculate a - b - borrow, returning the result and modifying the borrow value.
