Struct Conditional 

pub struct Conditional { /* private fields */ }

An \if… … \else … \or … \fi conditional the shape gate paired.

Implementations

impl Conditional

pub fn branches(&self) -> impl Iterator<Item = ConditionalBranch>

The branches, in source order — at least one, since the grammar opens a branch before the opener.

pub fn closer(&self) -> Option<Command>

The closing \fi, read positionally as the last child node rather than by matching the name: which control word closes a conditional is the grammar’s call, and re-deciding it here would be the same meaning check twice (decision #10). None only if the gate’s guarantee is ever broken, which callers must tolerate rather than assume away.
