Enum Period 

pub enum Period<'a> {
    Repeats(usize),
    Cycles(usize),
    Walks {
        len: usize,
        base: usize,
        steps: &'a [Steps],
    },
}

How a mapping’s positions read the same items again (Mapping::period).

Variants

Repeats(usize)

Each item repeats over this many consecutive positions.

Cycles(usize)

Every this many positions read the source’s first items again, in order, as Tiled reads them.

Walks

Every len positions read the same items again, through entries: those that steps reach from base. Reading a cycle in place walks its entries, so a reader gathers one cycle first (tiled_cycle).

Fields

len: usize

base: usize

steps: &'a [Steps]

Implementations

impl Period<'_>

pub fn tiling(&self, run: usize) -> Option<(usize, usize)>

The period and exact backing length written by tiled_cycle for this run size. Long plain cycles return None; long walking cycles are stored once.
