rustdoc: Add option to persist doc test executables Fixes #37048. This is the initial version of the code so the doctest executables can be used for stuff like code coverage (specifically https://github.com/xd009642/tarpaulin/issues/13) the folders it goes into were just a first idea, so any better ones are welcome. Right now it creates a directory structure like: ``` given_path/ |_____ <filename>_rs_<linenum>/ |_____ ... |_____ <filename>_rs_<linenum>/ |_____ rust_out ``` I couldn't figure out where it actually outputs the file w/ the name, I suspect its somewhere deeper in the compiler. It also adds the unstable `--persist-doctests` flag to `rustdoc` that enables this behavior.
This directory contains the source code of the rust project, including:
rustcand its testslibstd- Various submodules for tools, like rustdoc, rls, etc.
For more information on how various parts of the compiler work, see the rustc guide.
There is also useful content in the following READMEs, which are gradually being moved over to the guide:
