CustomDetHash¶
class CustomDetHash
det_hash_object¶
class CustomDetHash:
| ...
| def det_hash_object(self) -> Any
By default, det_hash() pickles an object, and returns the hash of the pickled
representation. Sometimes you want to take control over what goes into
that hash. In that case, implement this method. det_hash() will pickle the
result of this method instead of the object itself.
If you return None, det_hash() falls back to the original behavior and pickles
the object.
DetHashFromInitParams¶
class DetHashFromInitParams(CustomDetHash)
Add this class as a mixin base class to make sure your class's det_hash is derived exclusively from the parameters passed to init().
det_hash_object¶
class DetHashFromInitParams(CustomDetHash):
| ...
| def det_hash_object(self) -> Any
DetHashWithVersion¶
class DetHashWithVersion(CustomDetHash)
Add this class as a mixing base class to make sure your class's det_hash can be modified
by altering a static VERSION member of your class.
VERSION¶
class DetHashWithVersion(CustomDetHash):
| ...
| VERSION = None
det_hash_object¶
class DetHashWithVersion(CustomDetHash):
| ...
| def det_hash_object(self) -> Any
det_hash¶
def det_hash(o: Any) -> str
Returns a deterministic hash code of arbitrary Python objects.
If you want to override how we calculate the deterministic hash, derive from the
CustomDetHash class and implement det_hash_object().
