Struct andys_morning_stroll::Decisions

pub struct Decisions { /* private fields */ }

A helper struct to assist with iterating through the possible choices of path.

We are essentially counting in base 3. For simplicity, we’re using an array of 20 usize integers.

To be cleaner, this should probably implement Iterator from the standard library.

Implementations

impl Decisions

pub fn new() -> Self

Create a new decision iterator.

pub fn curr(&self) -> &[usize; 20]

Return the current value of the array representation of our path.

pub fn inc(&mut self)

Increment to the next path.
