Rust support for Visual Studio 2017 15.8+

Adds language support for Rust to Visual Studio 2017. Supports:

• code completion
• goto definition
• find all references
• error squiggles
• code action (lightbulb)
• hover
• formatting
• rename

Rust support is powered by the Rust Language Server (RLS).

Please note that this extension is very early in development, there may be bugs or rough edges.

Quick Start

• Install a build of Visual Studio (15.8 preview 3 or newer).
• Install rustup (Rust toolchain manager).
• Install this extension from the marketplace
• Open a Rust project (File > Open Folder...). Open the folder for the whole project (i.e., the folder containing 'Cargo.toml'), not the 'src' folder.
• The extension will start when you open a Rust file. You'll be prompted to install the RLS. Once installed, the RLS should start building your project.
