Enum MathNodeList

pub enum MathNodeList<ET: EngineTypes> {
    Simple(Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>),
    Over {
        top: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>,

Expand description

An open list of unresolved math nodes. TODO: rethink this

Variants§

§

Simple(Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>)

A simple list of nodes

§

Over

An open list after encountering an \over or \above or \atop or a related command. The current list up to that point is moved to the top, subsequent nodes are added to bottom. (see MathNode::Over

§

EqNo

An open list after encountering an \eqno or \leqno. The current list up to that point is moved to main, subsequent nodes are added to eqno. This can only happen, if this list’s direct “parent” is a horizontal (i.e. non-math) list.
