Struct ListTarget 

pub struct ListTarget<ET: EngineTypes, N>(/* private fields */);

Once a node list is closed, something is supposed to happen to it; most commonly, it is a box-list; but occasionally, something else should happen to it - e.g. \vadjust{...} adds the list’s contents as a vertical adjustment, a^{...} adds it to the superscript-field of the a.character etc. This struct abstracts over that by carrying a continuation function to be called when the list is closed.

TODO: rethink this in light of BoxTarget.

Implementations

impl<ET: EngineTypes, N> ListTarget<ET, N>

pub fn new<F: FnOnce(&mut EngineReferences<'_, ET>, Vec<N>, SourceRef<ET>) -> TeXResult<(), ET> + 'static>( f: F, ) -> Self

Create a new list target from the given continuation function.

pub fn call( self, engine: &mut EngineReferences<'_, ET>, v: Vec<N>, start: SourceRef<ET>, ) -> TeXResult<(), ET>

Execute the continuation function (once the list is closed)

pub fn none() -> Self

Create a trivial list target

pub fn is_some(&self) -> bool

Whether the continuation function has not yet been called
