impl<I: Interner> Debug for ProgramClause<I>
sourceimpl<I: Interner> Fold<I> for ProgramClause<I>
impl<I: Interner> Fold<I> for ProgramClause<I>
Folding a program clause invokes the fold_program_clause
callback on the folder (which will, by default, invoke the
super_fold_with
method on the program clause).
type Result = ProgramClause<I>
type Result = ProgramClause<I>
The type of value that will be produced once folding is done.
Typically this is Self
, unless Self
contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T
value where T: Fold
, in which case
you get back a T
, not a &T
). Read more
