Struct Nonce

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

A random nonce (“number used once”).

Implementations

impl Nonce

pub const NONCE_SIZE: usize = 12usize

pub fn new() -> Self

Create a new random nonce.

pub const fn from_data(data: [u8; 12]) -> Self

Restores a nonce from data.

pub fn from_data_ref(data: impl AsRef<[u8]>) -> Result<Self>

Restores a nonce from data.

pub fn data(&self) -> &[u8; 12]

Get the data of the nonce.

pub fn from_hex(hex: impl AsRef<str>) -> Self

Create a new nonce from the given hexadecimal string.

Panics

Panics if the string is not exactly 24 hexadecimal digits.

pub fn hex(&self) -> String

The data as a hexadecimal string.

Trait Implementations

impl AsRef<Nonce> for Nonce

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl CBORTagged for Nonce

fn cbor_tags() -> Vec<Tag>

The CBOR tags assocated with this type. If more than one tag is present, they are considered equivalent for reading, but only the first one is used for writing.

impl CBORTaggedDecodable for Nonce

fn from_untagged_cbor(untagged_cbor: CBOR) -> Result<Self>

Creates an instance of this type by decoding it from untagged CBOR.

fn from_tagged_cbor(cbor: CBOR) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from tagged CBOR.

fn from_tagged_cbor_data(data: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded tagged CBOR.

fn from_untagged_cbor_data(data: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded untagged CBOR.

impl CBORTaggedEncodable for Nonce

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

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

Returns the tagged value in CBOR binary representation.

impl Clone for Nonce

fn clone(&self) -> Nonce

Returns a copy 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 Default for Nonce

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a Nonce> for &'a [u8; 12]

fn from(value: &'a Nonce) -> Self

Converts to this type from the input type.

impl From<&Nonce> for Nonce

fn from(nonce: &Nonce) -> Self

Converts to this type from the input type.

impl From<&Nonce> for Vec<u8>

fn from(nonce: &Nonce) -> Self

Converts to this type from the input type.

impl From<Nonce> for CBOR

fn from(value: Nonce) -> Self

Converts to this type from the input type.

impl From<Nonce> for Vec<u8>

fn from(nonce: Nonce) -> Self

Converts to this type from the input type.

impl From<Rc<Nonce>> for Nonce

fn from(value: Rc<Nonce>) -> Self

Converts to this type from the input type.

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 TryFrom<CBOR> for Nonce

type Error = Error

The type returned in the event of a conversion error.

fn try_from(cbor: CBOR) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Nonce

impl StructuralPartialEq for Nonce
