A backend that wraps another backend with a caching scheme.

Source: R/backend-cached.R

The cache is stored in files named based on dataset and underlying backend hashes, within the given directory, you can use cached_fit_filename() to manually access the cache.

SBC_backend_cached(cache_dir, backend)

Arguments

cache_dir

directory where the cache files (one file per fit) will be stored

backend

any other backend that does the actual computation

Details

The cached fit will try to re-emit all output, warnings and messages. The ordering within each category is preserved, but the relative ordering of e.g. outputs vs. messages (and all other combinations) may not be.
