Subject: [PATCH v14 0/2] rust: xarray: Add a minimal abstraction for XArray
Date: Tue, 17 Dec 2024 10:28:16 -0500 [thread overview]
Message-ID: <20241217-rust-xarray-bindings-v14-0-9fef3cefcb41@gmail.com> (raw)
This is a reimagining relative to earlier versions[0] by Asahi Lina and
Maíra Canal.
It is needed to support rust-binder, though this version only provides
enough machinery to support rnull.
