rs-teststand

Safe, idiomatic Rust bindings (twin API) for the National Instruments TestStand™ COM API.

use rs_teststand::Engine;

fn main() -> Result<(), rs_teststand::Error> {
    let engine = Engine::new()?;
    println!("TestStand {}", engine.version_string()?);
    Ok(())
}

• Twin API, type names, hierarchy, method names, and parameter order follow the TestStand™ COM API, so anyone who knows TestStand™ can predict the call.
• Memory safe: this crate is #![forbid(unsafe_code)]; all COM interop is confined to the audited rs-teststand-sys crate. COM references are released deterministically on drop, and single-threaded-apartment pointers cannot cross threads by construction.
• No panics in library code, every fallible member returns Result<_, rs_teststand::Error>.

Windows only. Requires a registered TestStand™ engine at runtime (2016, 2026, 32- or 64-bit); no TestStand™ installation is needed to build.

See the repository for the roadmap and contribution guide. For authoritative API semantics, refer to National Instruments' own TestStand™ API Reference documentation.
