Overview

Filesystem persistence implementations for lib3h and holochain. Provides content addressable storage (CAS) and entity attribute value (index) associations using hiearchical based filesystem storage.

Usage

Add lib3h_persistence_file crate to your Cargo.toml. Below is a stub for creating a storage unit and adding some content.

use lib3h_persistence_file::cas::file::FilesystemStorage;
use tempfile::tempdir;

pub fn init() -> FilesystemStorage {
  let dir = tempdir().expect("Could not create a tempdir for CAS.");
  let store = FilesystemStorage::new(dir.path()).unwrap();
  store.add(<some_content>).expect("added some content");
  store
}
