👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

DittoMutDocuments can be obtained within update calls (PendingIdSpecificOperation::update or PendingCursorSpecificOperation::update).

Required Methods

fn get_mut<'doc, V: MutableValue<'doc>>( &'doc mut self, path: &str, ) -> Result<V, DittoError>

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Returns the value at a given path in the mutable document.

The parameter V represents the type expected at the given path. Note however that other peers may have changed this type and deserialization may fail.

fn set<V: Serialize>(&mut self, path: &str, val: V) -> Result<(), DittoError>

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Assigns a some serializable value to the document at the given path and removes any other information present at that path.

If the path does not exist it will be created.

fn set_as_default<V: Serialize>( &mut self, path: &str, val: V, ) -> Result<(), DittoError>

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Sets the value at the provided path and marks it as the default, indicating other peers in the network are expected to overwrite it.

fn remove(&mut self, path: &str) -> Result<(), DittoError>

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Remove the value from a document at a given path

fn increment(&mut self, path: &str, amount: f64) -> Result<(), DittoError>

👎Deprecated: Use ditto.store().execute_v2(...) or ditto.store().register_observer_v2(...) instead

Increment (+/-) a counter by amount.

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.
