Adding more detailed suggestions

[szabgab]

Once in a while I feel that the explanations of the lints could include more suggestions. e.g print_stdout could include the suggestion to replace the debugging print statement with log::debug!

Something like this:

One solution would be to convert the print-statements into a logging calls. For this you'll need to add the log create and one of the loggers and replace println!() by log::debug!()

I'd be happy to send such extensions whenever encounter something, assuming the general concept of giving more detailed suggestion is something that is seen as positive.

We are usually careful with suggesting external crates, as we don't want to put the impression, that we favor one crate over another.

For logging: Why suggest log over any of the other logging crates?

So I wouldn't put this in the lint suggestion, but we could include this information in the lint documentation and either link the awesome-rust page or the rust-cookbook which is a bit more official.

EDIT: Just saw that the last commit to the cookbook was 3 years ago, so maybe not that

As I now seem to understand there is some explanation that comes with clippy and is printed on the terminal and there is more information on the web site that clippy refers to. I need to understand the separation between the two, but I was thinking about the web site.

Maybe the link should be to the logging crates as mentioned above or to to the logging tag on crates.io So:

One solution would be to convert the print-statements into logging calls using one of the logging crates.

explanation that comes with clippy and is printed on the terminal

With that I meant the normal error message format, that you also get from rustc.

However, there is also clippy-driver --explain clippy::almost_swapped, that prints the documentation that is also available on the web.

Adding a link to crates.io sounds good to me. Great idea! Feel free to open a PR about this.
