Struct aoc::year2021::day23::Hallway

struct Hallway {
    packed: usize,
}

Pack the state of the hallway into a usize. Each hallway position is represented by a nibble with the pod type (plus additionally empty or room entrance markers) for a total of 44 bits.

Fields

packed: usize

Implementations

impl Hallway

fn new() -> Hallway

The initial hallway is empty. Room entrances are marked as type 4.

fn get(self, index: usize) -> usize

Find the amphipod at a specific location.

fn set(&mut self, index: usize, value: usize)

Updated the amphipod at a specific location.

Trait Implementations

impl Clone for Hallway

fn clone(&self) -> Hallway

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for Hallway

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Hallway

fn eq(&self, other: &Hallway) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
