Struct MapMut 

pub struct MapMut<'a> { /* private fields */ }

Mutable reference to a Map CRDT.

Obtained through Transaction::root() or Transaction::get_map_mut().

Implementations

impl<'a> MapMut<'a>

pub fn id(&self) -> CrdtId

Get the CRDT ID for this map.

pub fn is_root(&self) -> bool

Check if this is the root map.

pub fn set(&mut self, key: &str, value: impl Into<PrimitiveValue>)

Set a key to a primitive value.

Accepts any type that implements Into<PrimitiveValue>: bool, i64, i32, String, &str, or () for nil.

To create nested CRDTs, use create_map(), create_text(), create_set(), or create_register() instead.

pub fn set_nil(&mut self, key: &str)

Set a key to nil (tombstone).

In CRDT semantics, this creates a tombstone - the key still exists but has a nil value. Use get() to check if a value is nil, or use get_conflicted() to see if there are concurrent non-nil values.

Note: contains_key() will still return true after this operation.

pub fn create_map(&mut self, key: &str) -> CrdtId

Create a nested Map at the given key.

Returns the CRDT ID of the new map, which can be used with Transaction::map_by_id() to get a mutable reference.

pub fn create_text(&mut self, key: &str) -> CrdtId

Create a nested Text CRDT at the given key.

Returns the CRDT ID of the new text.

pub fn create_set(&mut self, key: &str) -> CrdtId

Create a nested Set CRDT at the given key.

Returns the CRDT ID of the new set.

pub fn create_register(&mut self, key: &str) -> CrdtId

Create a nested Register CRDT at the given key.

Returns the CRDT ID of the new register.
