----------------------------------
Summary: [Rust] Allow Position to support arbitrary Cursor type
Key: ARROW-8170
URL: https://issues.apache.org/jira/browse/ARROW-8170
Project: Apache Arrow
Issue Type: Improvement
Components: Rust
Affects Versions: 0.16.0
Reporter: Jeong, Heon
Hi, I'm currently writing in-memory page writer in order to support buffered
row group writer (just like in C++ version), and...
* I'd like to reuse SerializedPageWriter
* SerializedPageWriter requires sink supports util::Position (which is private)
* There's Position impl for Cursor, but unnecessarily restricts to mutable
references for internal type.
So I'd like to make one line change in order to lift that type restriction and
allow me implementation.
