Encodes an integer as bytes

Required Associated Types

type Bytes: ByteArray

Byte array that fits the whole encoded integer

Required Methods

fn to_be_bytes(&self) -> Self::Bytes

Encodes integer as bytes in big-endian byte order

fn to_le_bytes(&self) -> Self::Bytes

Encodes integer as bytes in little-endian byte order

fn from_be_bytes_exact(bytes: &Self::Bytes) -> Option<Self>

Decodes integer encoded as bytes in big-endian bytes order

Returns None if the bytes don’t correspond to a valid integer.

fn from_le_bytes_exact(bytes: &Self::Bytes) -> Option<Self>

Decodes integer encoded as bytes in little-endian bytes order

Returns None if the bytes don’t correspond to a valid integer.

fn from_be_bytes_mod_order(bytes: &[u8]) -> Self

Interprets bytes as big-endian encoding of an integer. Returns integer mod curve (prime) order.

fn from_le_bytes_mod_order(bytes: &[u8]) -> Self

Interprets bytes as little-endian encoding of an integer. Returns integer mod curve (prime) order.

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.
