Syntastic integration: rustc not enabled as a checker

[jmatraszek]

Using rustc stable (1.12.0), Vim 8.0, rust.vim 2030019 and Syntastic 3.7.0-243.
SyntasticInfo output:

Syntastic version: 3.7.0-243 (Vim 800, Linux, GUI)
Info for filetype: rust
Global mode: active
Filetype rust is active
The current file will be checked automatically
Available checker: rustc
Currently enabled checkers: -  

Nothing happens on save or calling SyntasticCheck.

After running let g:syntastic_rust_checkers = ['rustc'] works as expected. Right now I am using autocmd FileType rust let g:syntastic_rust_checkers = ['rustc'] in .vimrc as a workaround.

P.S. I know there is a bunch of other Syntastic related issues, but all of them seems to be different (problems with error format, rustc is enabled as a checker but still does not work etc. etc.).

I experienced the same issue with rustc 1.12.1, Vim 8.0.55, rust.vim 59e5e2f, and Syntastic 3.8.0-3.
SyntasticInfo output:

Syntastic version: 3.8.0-3 (Vim 800, Darwin)
Info for filetype: rust
Global mode: active
Filetype rust is active
The current file will be checked automatically
Available checker: rustc
Currently enabled checkers: -

The workaround posted above worked for me (thanks @jmatraszek!)

@jmatraszek is autocmd FileType rust really necessary? Shouldn't Syntastic itself manage filetypes?

Thanks for the workaround.

I experience the same issue with rust.vim eed97e7, rustc 1.15.0 (nightly daf8c1dfc) and rustc 1.13.0, Vim 8.0, Syntastic 3.8.0-2.

Syntastic version: 3.8.0-2 (Vim 800, Linux, GUI)

Just chiming in to say that I had to do the same as others in this issue to solve this issue.

let g:syntastic_rust_checkers = ['rustc'] inside my vimrc.

[ajcrites]

While this generally works, Syntastic will report errors for extern crate .... Is there any way to suppress this?

[shibotto]

@ajcrites if you have cargo>=0.16 you can use it instead of rustc. Unfortunately cargo support is not yet merged in rust.vim but you can manually merge (aka copy-paste) it from one of this two pull request:

#147
#132

then check if it is detected with :SyntasticInfo and if everything is fine you can add let g:syntastic_rust_checkers = ['cargo'] to your .vimrc. I'm using it and it seems to work fine.

Would be great to see one of these pull requests get accepted. I found this from looking to see if cargo check was supported yet since I've been having to disable Syntastic now that my project has gotten large enough that it takes notable time to compile. Cargo check however is just a couple of seconds or so.

Same here for rust 1.22. Workaround is working fine. Would be good to put it on the readme at least.
Thanks anyway!

Anyone driving by, #132 was merged. Just setting let g:syntastic_rust_checkers = ['cargo'] in your vimrc will get you cargo check running on saves.

This could probably be closed.

let g:syntastic_rust_checkers = ['cargo'] is now the default if nothing is specified. Thanks!
