Field element helpers Unless otherwise stated everything is in little-endian byte order.

Required Methods

fn from_bytes(bytes: &[u8]) -> Result<F>

Deserialize from bytes

Errors

Returns error if deserialization fails.

fn from_hex(hex: &str) -> Result<F>

Deserialize from little-endian hex

Errors

Returns error if hex decoding or deserialization fails.

fn from_bits(bits: &[bool]) -> Result<F>

Deserialize from bits

Errors

Returns error if deserialization fails.

fn to_bytes(&self) -> Vec<u8>

Serialize to bytes

fn to_hex(&self) -> String

Serialize to hex

fn to_bits(&self) -> Vec<bool>

Serialize to bits

fn bits_to_field(&self, start: usize, end: usize) -> Result<F>

Create a new field element from this field elements bits

Errors

Returns error if deserialization fails.

Provided Methods

fn from_biguint(big: &BigUint) -> Result<F>

where F: PrimeField,

Deserialize from BigUint

Errors

Returns error if conversion fails.

fn to_biguint(&self) -> BigUint

where F: PrimeField,

Serialize field element to a BigUint

fn to_bigint_positive(&self) -> BigInt

where F: PrimeField,

Serialize field element f to a (positive) BigInt directly.

fn size_in_bytes() -> usize

where F: PrimeField,

Field size in bytes

fn modulus_biguint() -> BigUint

where F: PrimeField,

Get the modulus as BigUint

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
