}

Minimal CRUD and supersession surface shared by local and enterprise stores.

Required Methods

fn get(&self, object_id: &str) -> Option<KnowledgeObjectV1>

Fetch a content-addressed object by its stable object id.

fn put(&mut self, object: KnowledgeObjectV1) -> Result<(), KnowledgeStoreError>

Insert or replace an object.

fn query(&self, query: &KnowledgeQuery) -> Vec<KnowledgeObjectV1>

Return objects matching every supplied filter.

fn supersede( &mut self, old_object_id: &str, replacement: KnowledgeObjectV1, ) -> Result<(), KnowledgeStoreError>

Store a replacement and link the old object to it through ValidityWindow::superseded_by.

fn delete(&mut self, object_id: &str) -> bool

Delete an object and report whether it existed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
