WithMeta

class utilipy.utils.WithMeta(wrapped: Any, **kw)[source]

Bases: ObjectProxy

Objects wrapt to include metadata.

This is an ObjectProxy for thin and light wrappers.

  • Thin: All operations are carried to the wrapt value,

    except for self.meta, which accesses the meta attribute.

  • Light: operations do not carry the metadata

    >>> x = WithMeta(2)
>>> y = x + 2
>>> y.meta
