rustdoc fails after interrupting doc generation

[TheNeikos]

I tried this command:

cargo doc

I then pressed ctrl-c to stop it. I then re-ran it.

I expected to see this happen: It builds the documentation

Instead, this happened:

error: couldn't generate documentation: invalid template: invalid format: should have a newline on the last line
  |
  = note: failed to create or modify "/home/neikos/projects/software-suite/target/doc/search-index.js"

error: could not document `unicode-ident`
warning: build failed, waiting for other jobs to finish...
error: could not document `smallvec`
error: could not document `thiserror`

It seems like you're interrupting rustdoc while that file is being written.

unlike most build artifacts, the search index is currently persisted across rebuilds.

I believe that cargo doc should remove the search index before invoking rustdoc, as that would also solve #133544
