# Objective - Some workspace members do not inherit the global lints. ## Solution - Add a `[lints]` entry for all files returned by `rg --files-without-match -F "[lints]" **/Cargo.toml`, except the compile failure tests since these aren't part of the workspace. - Add some docstrings where needed. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
