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:

# use comrak::nodes::{AstNode, NodeValue};
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:

# use comrak::nodes::{Ast, AstNode, NodeValue};
let root = AstNode::from(Ast::new_with_sourcepos(
    NodeValue::Paragraph,
    (4, 1, 4, 10).into(),
));

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

# use comrak::{nodes::{AstNode, NodeValue}, Arena};
# let arena = Arena::new();
let node_in_arena = arena.alloc(NodeValue::Document.into());
