Utilities for navigating flat trees

Flat Trees are the core data structure that power Hypercore feeds. They allow us to deterministically represent a tree structure as a vector. This is particularly useful because vectors map elegantly to disk and memory. Because Flat Trees are deterministic and pre-computed, there is no overhead to using them. In effect this means that Flat Trees are a specific way of indexing into a vector more than they are their own data structure. This makes them uniquely efficient and convenient to implement in a wide range of languages.


$ pip install flat-tree


from flat_tree.accessor import FlatTreeIterator

tree_iter = FlatTreeIterator()
assert tree_iter.index == 0
assert tree_iter.parent() == 1
assert tree_iter.parent() == 3
