[jira] [Created] (ARROW-10040) [Rust] Create a way to slice
unalligned offset buffers
Neville Dipale created ARROW-10040:
--------------------------------------
Summary: [Rust] Create a way to slice unalligned offset buffers
Key: ARROW-10040
URL: https://issues.apache.org/jira/browse/ARROW-10040
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Affects Versions: 1.0.1
Reporter: Neville Dipale
We have limitations on the boolean kernels, where we can't apply the kernels on buffers whose offsets aren't a multiple of 8. This has the potential of preventing users from applying some computations on arrays whose offsets aren't divisible by 8.
We could create methods on Buffer that allow slicing buffers and copying them into aligned buffers.
An idea would be Buffer::slice(&self, offset: usize, len: usize) -> Buffer;
