Struct FixedLength

pub struct FixedLength<const L: usize>(/* private fields */);

An initialization vector that must be unique for the lifetime of the associated key it is used with.

Implementations

impl<const L: usize> FixedLength<L>

pub fn size(&self) -> usize

Returns the size of the iv in bytes.

pub fn new() -> Result<Self, Unspecified>

Constructs a new FixedLength from pseudo-random bytes.

Errors

• Unspecified: Returned if there is a failure generating L bytes.

Trait Implementations

impl<const L: usize> AsRef<[u8; L]> for FixedLength<L>

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

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

impl<const L: usize> Drop for FixedLength<L>

fn drop(&mut self)

Executes the destructor for this type.

impl<const L: usize> From<&[u8; L]> for FixedLength<L>

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

Converts to this type from the input type.

impl<const L: usize> From<[u8; L]> for FixedLength<L>

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

Converts to this type from the input type.

impl<const L: usize> TryFrom<&[u8]> for FixedLength<L>

type Error = Unspecified

The type returned in the event of a conversion error.

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

Performs the conversion.

impl<const L: usize> TryFrom<FixedLength<L>> for [u8; L]

type Error = Unspecified

The type returned in the event of a conversion error.

fn try_from(value: FixedLength<L>) -> Result<Self, Self::Error>

Performs the conversion.
