[jira] [Created] (ARROW-10041) [Rust] Possible to create
LargeStringArray with DataType::Utf8
Neville Dipale created ARROW-10041:
--------------------------------------
Summary: [Rust] Possible to create LargeStringArray with DataType::Utf8
Key: ARROW-10041
URL: https://issues.apache.org/jira/browse/ARROW-10041
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Affects Versions: 1.0.1
Reporter: Neville Dipale
We don't perform enough checks on ArrayData when creating StringArray and LargeStringArray. As they use different integer sizes for offsets, this can create a problem where Offset<Vec<i32>> could be correctly reinterpreted as Offset<Vec<i64>> and vice versa.
We should add checks that pervent this. The same might apply for List and LargeList
