Struct Nonce

pub struct Nonce(/* private fields */);

A 128-bit number used only once.

Needed when constructing Offer::metadata and deriving Offer::issuer_signing_pubkey from ExpandedKey. Must not be reused for any other derivation without first hashing.

Implementations

impl Nonce

pub const LENGTH: usize = 16usize

Number of bytes in the nonce.

pub fn from_entropy_source<ES: Deref>(entropy_source: ES) -> Self

where ES::Target: EntropySource,

Creates a Nonce from the given EntropySource.

pub fn as_slice(&self) -> &[u8]

Returns a slice of the underlying bytes of size Nonce::LENGTH.

Trait Implementations

impl Clone for Nonce

fn clone(&self) -> Nonce

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Nonce

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Nonce

fn eq(&self, other: &Nonce) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Readable for Nonce

fn read<R: Read>(r: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read.

impl TryFrom<&[u8]> for Nonce

type Error = ()

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, ()>

Performs the conversion.

impl Writeable for Nonce

fn write<W: Writer>(&self, w: &mut W) -> Result<(), Error>

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
