Variants

Insert

Insert a new subtree.

Fields

node: Node

Subtree, including caller-provided IDs.

placement: Placement

Destination.

InsertParent

Wrap a non-root node in a newly supplied leaf.

Fields

target: String

Existing child.

parent: Node

New parent (must have no children).

Remove(Vec<String>)

Remove nodes; selected descendants of selected ancestors are deduplicated.

Move

Move an ordered group, retaining all IDs.

Fields

ids: Vec<String>

Source IDs, ordered by document traversal.

placement: Placement

Destination.

Copy

Copy an ordered group, generating new IDs throughout every subtree.

Fields

ids: Vec<String>

Source IDs.

placement: Placement

Destination.

SetTopic

Replace a plain-text topic. Empty/whitespace-only edits are rejected.

Fields

id: String

Node ID.

topic: String

New text.

SetExpanded

Change visibility of a node’s descendants.

Fields

id: String

Node ID.

expanded: bool

New expansion state.

SetNote

Replace or clear a plain-text note. Blank notes are stored as None.

Fields

id: String

Node ID.

note: Option<String>

New note.

SetImage

Replace or clear a node picture.

Fields

id: String

Node ID.

image: Option<NodeImage>

New picture.

SetLayout(LayoutDirection)

Change document layout.

SetCompact(bool)

Change compact spacing.
