Struct dittolive_ditto::store::query_builder::DittoMutableRegister

pub struct DittoMutableRegister<'doc> { /* private fields */ }

Use doc.get_mut::<DittoMutableRegister>("...") to obtain a mutable CRDT register.

A mutable CRDT register can be updated while updating a document using .pending_cursor_op.update(...) or .pending_id_op.update(...).

Implementations

impl DittoMutableRegister<'_>

pub fn set<T: Serialize>(&mut self, value: T) -> Result<(), DittoError>

Set content of the register to a new value.

pub fn value<T: DeserializeOwned>(self) -> Result<T, DittoError>

Access to the value within the register.

The operation may fail if the content of the register can not be serialized into T.
