crdt_tree

A Conflict-free Replicated Data Type (CRDT) Tree written in Rust.

About

This crate aims to be an accurate implementation of the tree crdt algorithm described in the paper:

A highly-available move operation for replicated trees and distributed filesystems by M. Kleppmann, et al.

Please refer to the paper for a description of the algorithm's properties.

For clarity, data structures in this implementation are named the same as in the paper (State, Tree) or close to (OpMove --> Move, LogOpMove --> LogOp). Some are not explicitly named in the paper, such as TreeId,TreeMeta, TreeNode, Clock.
