Willow Data Model

This crate provides implementation of the Willow Data Model, including:

• Traits to assist in your implementation of Willow parameters, such as NamespaceId and SubspaceId.
• A zero-copy implementation of Willow paths and their constituent components.
• An implementation of Willow's entries.
• Utilities for Willow's entry groupings, such as ranges and areas
• Implementations of various relative encodings.

This crate does not yet have anything for Willow's concept of stores. Stay tuned!

Type parameters

Willow is a parametrised family of protocols, and so this crate makes heavy use of generic parameters.

The following generic parameter names are used consistently across this crate:

• MCL - A usize representing max_component_length.
• MCC - A usize representing max_component_count.
• MPL - A usize representing max_path_length.
• N - The type used for NamespaceId (willowprotocol.org), must implement the NamespaceId trait.
• S - The type used for SubspaceId (willowprotocol.org), must implement the SubspaceId trait.
• PD - The type used for PayloadDigest (willowprotocol.org), must implement the PayloadDigest trait.
• AT - The type used for AuthorisationToken (willowprotocol.org), must implement the AuthorisationToken trait.
