Support Cargo

[liigo]

This PR add the support of Cargo to Rust Linter. We try to find file Cargo.toml first, to decide which we should use it to lint the source file, cargo (if we found a Cargo.toml) or rustc (if not found). Both rustc and cargo's path are configurable.

We also need to improve Linter repo to complete this work. Currently, blocked by steelbrain/linter#290 and steelbrain/linter#304. These two PRs of mine are under reviewing.

Closes #4

update:
one limitation: when lint using cargo, you must save the editing file first. it is too expensive to copy the full cargo package to tmp directory, imo.

Thank you for your work, looks great.

Probably should use more understandable names of config variables, e.g. rustcPath and cargoPath

[liigo]

@gmist executablePath is used by upstream Linter. If i remove executablePath (and add rustcPath, cargoPath as you suggested) here, Linter will always add another executablePath in settings page, which looks weird. Maybe I'm wrong.

[liigo]

@dgriffen Fixed. Thank you!

Any updates on this?

@frewsxcv Blocked on steelbrain/linter#304.

Closing, 34ae462 was committed, already works for cargo.

Does it work for anybody on Windows? I'm using Cargo and currently getting an unresolved import error from the linter. I'm following this tutorial from the Rust book.

Edit:

Nevermind, I forgot to type the extern crate rand; part, it works okay now.
