pub fn affected_cache_root() -> Result<PathBuf>Expand description
Cache root for the cargo ktstr affected per-scheduler input-set cache.
Exposed as pub (unlike the crate-internal
resolve_cache_root_with_suffix) because the affected engine lives in
the cargo-ktstr BIN crate, a separate crate that reaches it as
ktstr::cache::affected_cache_root(). Runs the same KTSTR_CACHE_DIR ->
$XDG_CACHE_HOME -> $HOME/.cache cascade as every other ktstr cache,
under the affected suffix.
