Implementations

impl SolutionRange

pub const SIZE: usize

pub const MAX: Self

Maximum value

pub fn to_bytes(self) -> [u8; 8]

pub fn from_bytes(bytes: [u8; 8]) -> Self

Create a new instance from bytes

pub const fn from_pieces(pieces: u64, slot_probability: (u64, u64)) -> Self

Computes the following:

MAX * slot_probability / chunks * s_buckets / pieces

pub const fn to_pieces(self, slot_probability: (u64, u64)) -> u64
