pub struct TreeHandler { /* private fields */ }

Implementations

impl TreeHandler

pub fn new_detached() -> Self

Create a new container that is detached from the document.

The edits on a detached container will not be persisted/synced. To attach the container to the document, please insert it into an attached container.

pub fn delete(&self, target: TreeID) -> LoroResult<()>

pub fn delete_with_txn( &self, txn: &mut Transaction, target: TreeID ) -> LoroResult<()>

pub fn create<T: Into<Option<TreeID>>>(&self, parent: T) -> LoroResult<TreeID>

pub fn create_with_txn<T: Into<Option<TreeID>>>( &self, txn: &mut Transaction, parent: T ) -> LoroResult<TreeID>

pub fn mov<T: Into<Option<TreeID>>>( &self, target: TreeID, parent: T ) -> LoroResult<()>

pub fn mov_with_txn<T: Into<Option<TreeID>>>( &self, txn: &mut Transaction, target: TreeID, parent: T ) -> LoroResult<()>

pub fn get_meta(&self, target: TreeID) -> LoroResult<MapHandler>

pub fn get_node_parent(&self, target: TreeID) -> Option<Option<TreeID>>

Get the parent of the node, if the node is deleted or does not exist, return None

pub fn children(&self, target: TreeID) -> Vec<TreeID>

pub fn contains(&self, target: TreeID) -> bool

pub fn nodes(&self) -> Vec<TreeID>
