Implementations§

source§

impl<'a, 'tcx, Prov: Provenance, P: Projectable<'tcx, Prov>> ArrayIterator<'a, 'tcx, Prov, P>

source

pub fn next<M: Machine<'tcx, Provenance = Prov>>( &mut self, ecx: &InterpCx<'tcx, M>, ) -> InterpResult<'tcx, Option<(u64, P)>>

Should be the same ecx on each call, and match the one used to create the iterator.
