Feature request: WSL mode

Version of the extension: current master
OS: Windows 10

Description:

I want to install rust in wsl. I changed

vscode-rust/src/components/cargo/output_channel_task_manager.ts

Lines 59 to 65 in f78d234

	this.runningTask = new Task(
	this.configuration,
	this.logger.createChildLogger('Task: '),
	executable,
	args,
	cwd
	);

to

this.runningTask = new Task(
    this.configuration,
    this.logger.createChildLogger('Task: '),
    'wsl',
    [executable, ...args],
    cwd
);

set working directory to project root (at config)

and changed

vscode-rust/src/components/cargo/CargoTaskManager.ts

Lines 302 to 308 in f78d234

	const userWorkingDirectory = this._configuration.getCargoCwd();
	if (userWorkingDirectory !== undefined && userWorkingDirectory !== workingDirectory) {
	const manifestPath = join(workingDirectory, 'Cargo.toml');
	args = ['--manifest-path', manifestPath].concat(args);
	workingDirectory = userWorkingDirectory;
	}
	return { args, workingDirectory };

to

const userWorkingDirectory = this._configuration.getCargoCwd();
if (userWorkingDirectory !== undefined && userWorkingDirectory !== workingDirectory) {
    const manifestPath = correctPath(join(workingDirectory, 'Cargo.toml'));
    args = ['--manifest-path', manifestPath].concat(args);
    workingDirectory = userWorkingDirectory;
}
return { args, workingDirectory };

cargo check/build/test works well. But it's too hacky and it should be configurable.

I would also like to see support for Windows Subsystem for Linux in Windows 10. Here is the filepath that it's installed to when I follow the guidelines in the Rust website.

✗ whereis rustc
rustc: /home/damianrivas/.cargo/bin/rustc
✗ whereis cargo
cargo: /home/damianrivas/.cargo/bin/cargo

If you rely on the command line in any way, it's possible to run processes in WSL from the Windows environment like this (as an example):

CMD:

wsl.exe /home/damianrivas/.cargo/bin/cargo run

Explanation:

• wsl.exe: Recommended method to invoke WSL
• /home/damianrivas/.cargo/bin/cargo run: This is essentially cargo run

You can also convert between WSL and Windows versions of filepaths

$(wslpath 'C:\Users\Damian\rust\hello\hello.rs')

The above should return /mnt/c/users/Damian/rust/hello/hello.rs

• wlspath: A built-in interoperability WSL tool to convert between Unix and Windows paths.
• C:\Users\Damian\rust\hello\hello.rs: the Windows path where the file we want is located.

I hope this helps!
