Prolly publishes the prolly Rust library crate. Users depend on the package as prolly-map , while code imports stay concise: use prolly::{Config, Prolly}; . The crate provides content-addressed prolly tree storage primitives: an immutable, ordered key-value index over byte keys and byte values, with stable content-derived structure for efficient structural sharing, diff, merge, and bulk loading. At the API boundary, a Tree is a small persistent handle: root: Option<Cid> points at the content-addressed root node. config: Config records the chunking and encoding parameters used by the tree. The actual nodes live in a pluggable Store . Operations clone and rewrite only the affected path or subtrees, write new content-addressed nodes, and return a new Tree handle. All storage-backed tree work is implemented once by a runtime-neutral, async-first engine. AsyncProlly<S: AsyncStore> uses it directly; Prolly<S: Store> drives the same complete operation through an inline ready-only adapter.…
