Type Alias AstNode

pub type AstNode<'a> = Node<'a, RefCell<Ast>>;

The type of a node within the document.

It is bound by the lifetime 'a, which corresponds to the Arena nodes are allocated in. Child Asts are wrapped in RefCell for interior mutability.

You can construct a new AstNode from a NodeValue using the From trait:

let root = AstNode::from(NodeValue::Document);

Note that no sourcepos information is given to the created node. If you wish to assign sourcepos information, use the From trait to create an AstNode from an Ast:

let root = AstNode::from(Ast::new(
    NodeValue::Paragraph,
    (4, 1).into(), // start_line, start_col
));

Adjust the end position manually.

For practical use, you’ll probably need it allocated in an Arena, in which case you can use .into() to simplify creation:

let node_in_arena = arena.alloc(NodeValue::Document.into());
