make_key#
- gammapy.utils.cache.make_key(sig, *args, **kwargs)[source]#
Generate a unique hash key for caching based on normalized constructor arguments.
This function uses the signature of the class constructor (
__init__) to normalize the input arguments, serializes them usingray.cloudpickle, and returns a SHA-256 hash digest. The resulting key is suitable for use in caching mechanisms.- Parameters:
- siginspect.Signature
The signature of the method or function used to normalize arguments.
- *argstuple
Positional arguments to be normalized.
- **kwargsdict
Keyword arguments to be normalized.
- Returns:
- keystr
A SHA-256 hexadecimal digest representing the normalized arguments.
