Parameters for a leaf node that can be chosen by the application.

LeafNodeParametersBuilder

Builder for LeafNodeParameters.

ParentNode

RatchetTree

An exported ratchet tree as used in, e.g., GroupInfo.

RatchetTreeIn

A ratchet tree made of unverified nodes. This is used for deserialization and verification.

TreeSync

The TreeSync struct holds an MlsBinaryTree instance, which contains the state that is synced across the group, as well as the LeafNodeIndex pointing to the leaf of this group member and the current hash of the tree.

Enums

LeafNodeSource

The source of the LeafNode.

LeafNodeUpdateError

Leaf Node Update Error

Node

Container enum for leaf and parent nodes.

RatchetTreeError
