Upgrade PyO3 to 0.21
gi0baro opened this issue · comments
This also includes switching to new Bound
API.
See for ref PyO3/pyo3#3382 and PyO3/pyo3#3684
Note: check if GILPool
overhead is effectively removed in 0.21 and consider to use a forked version of PyO3 in the meantime if not (see PyO3/pyo3#3827 (comment) and PyO3/pyo3#3787 (comment))
