lisa.utils.FrozenDict#

class lisa.utils.FrozenDict(x, deepcopy=True, type_=<class 'dict'>)[source]#

Bases: Mapping

Read-only mapping that is therefore hashable.

Parameters:

  • deepcopy (bool) – If True, a deepcopy of the input will be done after applying type_.

  • type (collections.abc.Callable) – Called on the input to provide a suitable mapping, so that the input can be any iterable.

Note

The content of the iterable passed to the constructor is deepcopied to ensure non-mutability.

Note

Hashability allows to use it as a key in other mappings.
