Struct aoc::year2020::day14::Set

struct Set {
    ones: u64,
    floating: u64,
    weight: u64,
}

Fields

ones: u64

floating: u64

weight: u64

Implementations

impl Set

fn from(address: u64, value: u64, ones: u64, floating: u64) -> Set

The one bits are from the original address, plus any from the mask, less any that overlap with Xs.

fn intersect(&self, other: &Set) -> Option<Set>

Sets are disjoint if any 2 one bits are different and there is no X in either set.

The intersection of two masks looks like:

    First:  0011XXX
    Second: 0X1X01X
    Result: 001101X

fn size(&self) -> i64
