Enum advent_of_code_2021::day_12::CaveType

enum CaveType {
    START,
    END,
    SMALL,
    LARGE,
}

Track the four possible node types that dictate how they can be visited

Variants

START

First node in all valid paths, cannot be revisited

END

Last node in all valid paths, path instantly ends on visiting so implicitly can’t be revisited

SMALL

Can only be visited once, except in part two where a path can optionally revisit exactly one small node somewhere along its route

LARGE

Can be revisited any number of times, regardless of mode

Trait Implementations

impl Clone for CaveType

fn clone(&self) -> CaveType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaveType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&'_ str> for CaveType

fn from(s: &str) -> Self

start and end are specific strings, otherwise large vs small is determined by the case of the string

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
