Struct Day 

pub struct Day(/* private fields */);

A validated Advent of Code day, always within 1..=25.

The upper bound is the widest range any event has had; which days a particular event has is Year::has_day, enforced by Puzzle::new.

Implementations

impl Day

pub const FIRST: Self

The first puzzle day.

pub const LAST_FULL: Self

The last puzzle day of events up to and including 2024.

pub const LAST_SHORT: Self

The last puzzle day from Year::FIRST_SHORT on.

pub const fn new(day: u8) -> Option<Self>

Creates a day, rejecting anything outside 1..=25.

pub const fn clamped(year: Year, day: u32) -> Self

Clamps an arbitrary calendar day into the year’s puzzle range.

December has 31 days but only 25 puzzles - 12 from Year::FIRST_SHORT on - so anything past the end clamps to the last day of that event.

pub const fn get(self) -> u8

The underlying value.
