Enum subscript_compiler::backend::ast::Ast

pub enum Ast<'a> {
    Tag(Tag<'a>),
    Enclosure(Enclosure<'a, Ast<'a>>),
    Ident(Atom<'a>),
    Content(Atom<'a>),
    Token(Atom<'a>),
}

Variants

Tag(Tag<'a>)

Enclosure(Enclosure<'a, Ast<'a>>)

Some other enclosure, perhaps as a result of an error, such as in the case of curly braces or square parentheses thar Isn’t affiliated with a block node. Parentheses are fine though, since it’s used in math mode.

Ident(Atom<'a>)

Some identifier not followed by a block.

Content(Atom<'a>)

Token(Atom<'a>)
