-----------------------------
Summary: [Rust] Buffer equalities are incorrect
Key: ARROW-10042
URL: https://issues.apache.org/jira/browse/ARROW-10042
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 1.0.1
Reporter: Jorge
Two (byte) buffers are equal if their contents are equal.
However, currently, {{BufferData}} comparison ({{PartialEq}}) uses its
{{capacity}} as part of the comparison. Therefore, two slices are considered
different even when their content is the same but the corresponding
{{BufferData}} has a different capacity.
Since this equality is used by {{Buffer}}'s equality, which is used by all our
arrays, currently arrays are different when their contents are the same but the
underlying capacity is different. I am not sure that this is what we want.
