Marking as 1.0 -- some parts of this, e.g. collect
and at least a trait-ified collect_into
, we should have. The rest maybe not.
from rayon.
I'm interested in a collect_into()
that works on a bounded iterator. Hoping to be able to achieve something like:
items.par_iter()
.filter_map(func)
.collect_into(&mut existing_vec);
What is the compaction step you're talking about? It seems like it should be possible to tightly pack the vec being collected into using an atomic counter for the next index to write into.
from rayon.
@jwilm I'm going to open a separate issue for this. I'll spell out how I think it should work. An atomic counter is not needed.
from rayon.
(Closing because we now have a collect()
API)
