Provides both inherent and trait impls for a field element type which are backed by a core set of arithmetic functions specified as macro arguments.

Inherent impls

• const ZERO: Self
• const ONE: Self (multiplicative identity)
• pub fn from_be_bytes
• pub fn from_be_slice
• pub fn from_le_bytes
• pub fn from_le_slice
• pub fn from_uint
• fn from_uint_unchecked
• pub fn to_be_bytes
• pub fn to_le_bytes
• pub fn to_canonical
• pub fn is_odd
• pub fn is_zero
• pub fn double

NOTE: field implementations must provide their own inherent impls of the following methods in order for the code generated by this macro to compile:

• pub fn invert
• pub fn sqrt

Trait impls

• AsRef<$arr>
• ConditionallySelectable
• ConstantTimeEq
• ConstantTimeGreater
• ConstantTimeLess
• Default
• DefaultIsZeroes
• Eq
• Field
• PartialEq

Ops

• Add
• AddAssign
• Sub
