Build Status Docs GitHub release (latest by date)

Map a binary tree to a vector. Port of mafintosh/flat-tree

Installation

  1. Add the dependency to your shard.yml:

    dependencies:
      flat_tree:
        github: dukeraphaelng/flat_tree
    
  2. Run shards install

Usage

You can represent a binary tree in a simple flat list using the following structure

      3
  1       5
0   2   4   6  ...

This module exposes a series of functions to help you build and maintain this data structure

require "flat_tree"

list = [] of String

i = FlatTree.index(0_u64, 0_u64) # get array index for depth: 0, offset: 0
j = FlatTree.index(1_u64, 0_u64) # get array index for depth: 1, offset: 0

# use these indexes to store some data

list[i] = 'a'
list[j] = 'b'
list[FlatTree.parent(i)] = 'parent of a and b'
