fseval.types.CacheUsage

class fseval.types.CacheUsage(Enum):
    allow = 1
    must = 2
    never = 3

Determines how cache usage is handled. In the case of loading caches:

• allow: program might use cache; if found and could be restored
• must: program should fail if no cache found
• never: program should not load cache even if found

When saving caches:

• allow: program might save cache; no fatal error thrown when fails
• must: program must save cache; throws error if fails (e.g. due to out of memory)
• never: program does not try to save a cached version
