Enum PrettyNodeRole 

pub enum PrettyNodeRole {
    Syntax,
    Category,
    Token,
    Delimiter,
    Collection,
    Absent,
}

The semantic role of a PrettyNode.

This is presentation metadata rather than a replacement for the generated typed syntax hierarchy. It lets external renderers distinguish structural nodes, lexical leaves, delimiter boundaries, collection fragments, and absent optional values.

Variants

Syntax

A concrete node from the generated typed syntax hierarchy.

Category

A semantic category through which visitor specialization dispatches.

Token

A lexical token or virtual syntax leaf.

Delimiter

One boundary projected from a paired delimiter atom.

Collection

A transparent syntax container such as a list or delimiter pair.

Absent

An optional syntax value that is not present.
