Struct k256::arithmetic::Scalar

pub struct Scalar(_);

This is supported on feature="arithmetic" only.

An element in the finite field modulo n.

Methods

impl Scalar

pub const fn zero() -> Scalar

This is supported on feature="arithmetic" only.

Returns the zero scalar.

pub const fn one() -> Scalar

This is supported on feature="arithmetic" only.

Returns the multiplicative identity.

pub fn from_bytes(bytes: [u8; 32]) -> CtOption<Self>

This is supported on feature="arithmetic" only.

Attempts to parse the given byte array as an SEC-1-encoded scalar.

Returns None if the byte array does not contain a big-endian integer in the range [0, p).

pub fn to_bytes(&self) -> [u8; 32]

This is supported on feature="arithmetic" only.

Returns the SEC-1 encoding of this scalar.
