Support for procedural macro crate

[calebcartwright]

Hi @la10736, thanks for the report! Do you have a sample repo you could share?

If not, are you able to execute a specific test with a cargo test -p <<your package name>> --lib <<your test name>>

As long as the cargo test commands treat the target like a lib, then all we need to do to support that is determine what the associated target kind is in the cargo metadata output, and then plug that in to the existing list of target kinds that we associate to lib-like for test discovery and execution

vscode-rust-test-adapter/src/cargo.ts

Line 17 in ff077f2

const libTargetTypes = [ 'staticlib', 'dylib', 'cdylib', 'rlib' ];

You can try on my repo la10736/rstest. Anyway,

> cargo init simple_macro --lib
> cd simple_macro
> echo "
[lib]
proc-macro = true
" >> Cargo.toml

Now

michele@mdamico-laptop:~/sviluppo/simple_macro$ cargo test -p simple_macro

Thanks! You are correct, we can handle the proc-macro target kind like any other lib kind. I'll try to get an updated version of this published to the Marketplace later today

@la10736 - v0.9.0 has been published with support for the proc-macro target kind. Please give it a try whenever you get an opportunity, and feel free to re-open this if the issue persists.

Thanks again!
