qhyccd-rs

Crates.io Documentation Codecov Dependency status

libqhyccd bindings for Rust.

Current bindings are not complete, but will grow as functionality is needed for the ASCOM alpaca drivers or other projects. It is very early in the dev cycle and I am still learning a ton about Rust, so things might be in flux for a while.

[dependencies]
qhyccd-rs = "0.1.5"

Rust version requirements

qhyccd-rs works with stable Rust. The minimum required Rust version is 1.65.0.

Version of libqhyccd

Currently the library works with QHYCCD SDK 23.09.06 newer versions require openCV to be installed and do not link well necessarily on ARM-based systems. The focus of this development here is unix, specifically AARCH64-based flavors, although CI is testing for x64 compatibility as well.
