[Feature request] Add option to delete older files, while keeping latest building files.

[asuper0]

I don't know much about the target directory. As far as I can see, the folders ".fingerprint", "build", "deps", "incremental" in "target/debug" and "target/release" have a lot of files/directories that with same prefix name.

For example, some part of the result of command "tree" in a workspace is list below:

D:\CODE\MY-WORKSPACE\TARGET\DEBUG

The crate "accesskit" has file folders in ".fingerprint", with some suffix. We can image that only one of them is useful, and could be digged out by the timestamp. So it would be safe to delete other files to avoid rebuilding the project. I think this is a good way to solve #9 .

[marcospb19]

There is the '-s' and '-f' flags that should do just this, however, there are some caveats: #9 (comment)

Closing this for now but please reopen if necessary.

[asuper0]

Yes I read that before, and noticed the '-s' and '-f' would delete useful files.

When we change some code and build the project, we can image that the compiler will rebuild the changed part, and link them with other unchaned part. However, the '-s' and '-f' flag would delete the unchanged part, so cargo must rebuild them.
