> Nevertheless, may I still request a more structured way (like implemented in c++ library) of reading IPC file via mmap, which can be more ergnomic to use? @totoroyyb sounds like a good idea to figure out a better way to do this I noticed that `Mmap` implements `as_ref()` for `[u8]` https://docs.rs/memmap/latest/memmap/struct.Mmap.html#impl-AsRef%3C%5Bu8%5D%3E-for-Mmap So i think that means you can make a cursor over it like ```rust let cursor = std::io::Cursor::new(mmap.as_ref()); ``` And then you can use it with a FileReader - I am starting to work on improving the doc here: https://github.com/apache/arrow-rs/pull/6983 -- This is an automated message from the Apache Git Service.
