Implementations

impl Entropy

pub const LEN: usize = 32usize

The length of this data.

pub fn zero() -> Self

The instance will be equal to the left portion of left, suffixed with zeroes in case left is too short.

pub const fn len() -> usize

Return the length of this data in bytes.

pub fn to_vec(&self) -> Vec<u8>

Return a [$crate::Vec] with the same data as this.
