pub fn cache_path_for_source(language: &str, source: &str) -> Option<PathBuf>Expand description
Path where a compiled artefact for (language, source) should
land. The filename is <sha256-of-source>.wasm; collisions are
vanishingly unlikely and the hash also doubles as a cache key
for “is this source the same as last time?”.
Returns None only when cache_dir() is unavailable. The caller
can fall back to a tempfile in that case.
