no method named select_nth_unstable_by found for mutable reference &mut [T]

[Jeeesie]

rust toolchain is nightly-2020-04-22-x86_64-pc-windows-msvc unchanged - rustc 1.44.0-nightly
when I use 'cargo build ' to build the projects under path $Ballista_Home/rust
I meet the error :

error[E0599]: no method named select_nth_unstable_byfound for mutable reference&mut [T]in the current scope --> D:\cargo_home\git\checkouts\arrow-rs-3b86e19e889d5acc\08a662f\arrow\src\compute\kernels\sort.rs:883:36 | 883 | let (before, _mid, _after) = v.select_nth_unstable_by(limit, &mut is_less); | ^^^^^^^^^^^^^^^^^^^^^^ method not found in&mut [T]

select_nth_unstable_by is stabilized in a later rust version (1.49).
Could you upgrade the compiler version?

I also moved the issue to the arrow-rs repo as it originates there.

Yeah, resolved. Thanks for the quick answer.
