Struct grin_core::pow::Difficulty

pub struct Difficulty { /* fields omitted */ }

The difficulty is defined as the maximum target divided by the block hash.

Methods

impl Difficulty

pub fn zero() -> Difficulty

Difficulty of zero, which is invalid (no target can be calculated from it) but very useful as a start for additions.

pub fn one() -> Difficulty

Difficulty of one, which is the minimum difficulty (when the hash equals the max target)

pub fn from_num(num: u64) -> Difficulty

Convert a u32 into a Difficulty

pub fn to_num(&self) -> u64

Converts the difficulty into a u64
