pub const CACHE_DIR_NAME: &str = "__intersphinx_cache__";Expand description
The on-disk cache directory, relative to the doctree/cache directory
(app.doctreedir / '__intersphinx_cache__', _load.py:186-190). Sphinx
documents that “the location of this cache directory must not be relied
upon externally”; ours rides the fingerprint-wiped cache dir, so a
configuration change clears it along with everything else.
