Struct Nonce

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

A nonce for a single AEAD opening or sealing operation.

The user must ensure, for a particular key, that each nonce is unique.

Nonce intentionally doesn’t implement Clone to ensure that each one is consumed at most once.

Implementations

impl Nonce

pub fn try_assume_unique_for_key(value: &[u8]) -> Result<Self, Unspecified>

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

Fails if value isn’t NONCE_LEN bytes long.

Errors

error::Unspecified when byte slice length is not NONCE_LEN

pub fn assume_unique_for_key(value: [u8; 12]) -> Self

Constructs a Nonce with the given value, assuming that the value is unique for the lifetime of the key it is being used with.

Trait Implementations

impl AsRef<[u8; 12]> for Nonce

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

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

impl From<&[BigEndian<u32>; 3]> for Nonce

fn from(values: &[BigEndian<u32>; 3]) -> Self

Converts to this type from the input type.

impl From<&[LittleEndian<u32>; 3]> for Nonce

fn from(nonce: &[LittleEndian<u32>; 3]) -> Self

Converts to this type from the input type.

impl From<&[u32; 3]> for Nonce

fn from(values: &[u32; 3]) -> Self

Converts to this type from the input type.

impl From<&[u8; 16]> for Nonce

fn from(bytes: &[u8; 16]) -> Self

Converts to this type from the input type.

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

fn from(bytes: &[u8; 12]) -> Self

Converts to this type from the input type.
