Struct MindMapHandle 

pub struct MindMapHandle { /* private fields */ }

Copyable shared document handle. Mutation always passes through checked core transactions. Individual views own their viewport, editor and mounted nodes.

Implementations

impl MindMapHandle

pub fn document(self) -> Result<MindMapData, MindMapError>

Read a reactive persistent snapshot. No internal mutable signal is exposed.

pub fn selection(self) -> Result<Vec<String>, MindMapError>

Current selected IDs, reactively tracked.

pub fn revision(self) -> Result<u64, MindMapError>

Current generation, reactively tracked.

pub fn is_read_only(self) -> Result<bool, MindMapError>

Whether mutation is disabled.

pub fn set_before( self, hook: impl Fn(&Operation) -> bool + 'static, ) -> Result<(), MindMapError>

Set a synchronous veto hook. Invoked without a state borrow; reentrant mutations cause the outer operation to fail with StaleOperation.

pub fn clear_before(self) -> Result<(), MindMapError>

Clear the veto hook.

pub fn set_listener( self, listener: impl Fn(CoreEvent) + 'static, ) -> Result<(), MindMapError>

Install a host event listener. Events are delivered after releasing state.

pub fn apply( self, operation: Operation, ) -> Result<OperationResult, MindMapError>

Execute a checked mutation using the current before hook.

pub fn apply_with( self, operation: Operation, options: OperationOptions, ) -> Result<OperationResult, MindMapError>

Execute a checked mutation with explicit recording options.

pub fn select(self, ids: &[String]) -> Result<(), MindMapError>

Select existing IDs, including collapsed descendants.

pub fn set_read_only(self, value: bool) -> Result<(), MindMapError>

Enable/disable all document mutation entry points.

pub fn undo(self) -> Result<(), MindMapError>

Undo and restore selection.

pub fn redo(self) -> Result<(), MindMapError>

Redo and restore selection.

pub fn refresh(self, data: MindMapData) -> Result<(), MindMapError>

Validate and replace the document, clearing selection and history.

pub fn pending_edit(self) -> Result<Option<PendingEdit>, MindMapError>

The topic draft currently being edited, reactively tracked.

pub fn commit_pending(self) -> Result<bool, MindMapError>

Apply the pending draft as a normal undoable topic change and close the editor. Blank or unchanged drafts only close the editor. Returns whether the document changed. On failure the draft stays pending.

pub fn cancel_pending(self) -> Result<(), MindMapError>

Discard the pending draft and close the editor.

pub fn subscribe( self, listener: impl Fn(CoreEvent) + 'static, ) -> Result<Subscription, MindMapError>

Add an independent listener. Dropping the returned guard unsubscribes it.

pub fn register_plugin( self, plugin: Plugin, ) -> Result<PluginGuard, MindMapError>

Register a plugin for the lifetime of a guard. No document/history mutation.

pub fn set_plugin_enabled( self, id: &str, enabled: bool, ) -> Result<(), MindMapError>

Toggle an existing registration. Disabled capabilities disappear reactively.

pub fn has_plugin(self, capability: Capability) -> bool

Test an enabled capability for this document only.

pub fn plugin_commands(self) -> Result<Vec<Command>, MindMapError>

Commands supplied by enabled plugins.
