pub fn lookup_meaning(token: &Token) -> Option<Stored>Expand description
Get the “Meaning” of a token.
For active control sequences this may give the definition object (if
defined) or another token (if \let) or None. Any other token is returned
as is — which is what makes a \let-style comparison between a control
sequence and a character token work.
Clones the stored meaning; use with_meaning when inspecting it is enough.
