Enum MathNodeList

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

        bottom: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>,

        eqno: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>,
    },
}

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

Fields

top: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

sep: Option<ET::Dim>

bottom: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

left: Option<(ET::Char, UnresolvedMathFontStyle<ET>)>

right: Option<(ET::Char, UnresolvedMathFontStyle<ET>)>

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.

Fields

pos: EqNoPosition

main: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

eqno: Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

Implementations

impl<ET: EngineTypes> MathNodeList<ET>

pub fn push(&mut self, n: MathNode<ET, UnresolvedMathFontStyle<ET>>)

Push a node to the list.

pub fn close( self, start: SourceRef<ET>, end: SourceRef<ET>, ) -> (Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>, Option<(EqNoPosition, Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>)>)

Close the list, returning the list of nodes and the optional eqno.

pub fn list_mut( &mut self, ) -> &mut Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

Get the “open” list that nodes should be added to mutably

pub fn list(&self) -> &Vec<MathNode<ET, UnresolvedMathFontStyle<ET>>>

Get the “open” list that nodes should be added to immutably
