zarrs_sqlite

An SQLite-based Zarr store for the zarrs ecosystem.

Work in progress; see the specification proposal.

Usage

/// `None` would build an in-memory database.
let mut builder = zarrs_sqlite::TursoStore::builder(Some("path/to/file.zarrdb"));

// By default, this will be read-only and the database must already exist.

// The below allows the builder to create a new database, and truncates any existing database.
builder.create().truncate();

let inner = builder.build().await.unwrap();
let store: zarrs::storage::AsyncReadableWritableListableStorage = Arc::new(inner);
