rust-index: remove one collect when converting back...

rust-index: remove one collect when converting back Turns out this is slightly faster. Sending the results back to Python is still the most costly (like 75% of the time) of the whole method, but it's about as fast as it can be now. hg perf::phases on mozilla-try-2023-03-22 before: 0.267114 after: 0.247101

mercurial/thirdparty/cbor/README.rst

This library provides encoding and decoding for the Concise Binary Object Representation (CBOR) (RFC 7049) serialization format.

There exists another Python CBOR implementation (cbor) which is faster on CPython due to its C extensions. On PyPy, cbor2 and cbor are almost identical in performance. The other implementation also lacks documentation and a comprehensive test suite, does not support most standard extension tags and is known to crash (segfault) when passed a cyclic structure (say, a list containing itself).
