JSON document storage (WASI JSON DB).

Default WASM implementations delegate to wasi:jsondb via omnia-wasi-jsondb.

Required Methods

fn get( &self, store: &str, id: &str, ) -> impl Future<Output = Result<Option<Document>>> + Send

Fetch a document by id.

fn insert( &self, store: &str, doc: &Document, ) -> impl Future<Output = Result<()>> + Send

Insert a new document (fails if the id already exists).

fn put( &self, store: &str, doc: &Document, ) -> impl Future<Output = Result<()>> + Send

Upsert a document by id.

fn delete( &self, store: &str, id: &str, ) -> impl Future<Output = Result<bool>> + Send

Delete a document by id. Returns whether a document was removed.

fn query( &self, store: &str, options: QueryOptions, ) -> impl Future<Output = Result<QueryResult>> + Send

Query documents in a collection.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
