EnricoMi opened a new pull request, #6472:
URL: https://github.com/apache/arrow-rs/pull/6472
# Which issue does this PR close?
Together with #6462 fixes #6471.
# Rationale for this change
Data coming from Python could be misaligned. Using them will fail (see
#6471):
Memory pointer from external source (e.g, FFI) is not aligned with the
specified scalar type.
Before importing buffer through FFI, please make sure the allocation is
aligned.
Costly copying the data is better than failing and not being able to use the
data.
# What changes are included in this PR?
Call existing `ArrayData.align_buffers` right after array data are retrieved
via FFI (as suggested by the error message).
# Are there any user-facing changes?
Data become useable.
