POC: Rust Wrapper for 1DS C++ SDK

[CDFriend]

What is this?

Adds a Rust "wrapper" to the 1DS C++ SDK, which will allow the SDK to be imported into Rust projects as a crate. The crate interacts with the C API of the SDK (instead of C++) as this will ensure a stable binary interface between the Rust layer and C++ layer of the project.

Project Structure

Crates:

• cpp-client-telemetry-sys: crate directly exposing the C API of the 1DS SDK to Rust.
• oneds-telemetry: contains some abstractions over the 1DS SDK and allows messages to be sent to the SDK from the log crate.
• telemetry-sample: example executable using the oneds-telemetry crate.

Limitations

• Currently only i64 and string telemetry fields are supported.
• Currently we're only linking with the Windows-x64 static library - additional work on the build script will be required to add support for dynamic linking and other architectures/operating systems.

Build Instructions

1. Follow instructions in the root of the repository to build the project in Win32-Lib configuration for the x64 arch.
2. Run cargo build in wrappers/rust
