Fields

kind: CstNodeKind

What kind of syntax element this node represents.

span: Span

content_span: Span

Span of just the meaningful content (excluding leading/trailing trivia that belongs to this node).

children: Vec<NodeId>

Children of this node (indices into the arena).

parent: Option<NodeId>

Parent node (None only for the Root).

field_name: Option<Span>

For Field / Import nodes: span of the field name.

field_value: Option<Span>

For Field / Import nodes: span of the field value (first line only; continuation lines are child ValueLine nodes).

section_keyword: Option<Span>

For Section nodes: span of the section keyword.

section_arg: Option<Span>

For Section nodes: span of the section argument (e.g. my-exe).

condition_keyword: Option<Span>
