`qualtran.symbolics.types.HasLength`

qualtran.symbolics.HasLength(
    n
)

This is used as a “symbolic” tuple. The length can either be a positive integer or a sympy expression. For example, if a bloq attribute is a tuple of ints, we can use the type:

values: Union[tuple, HasLength]

For the symbolic variant of a NDArray, see Shaped.

Note that we cannot override len and return a sympy symbol because Python has special treatment for len and expects you to return a non-negative integers.

See https://docs.python.org/3/reference/datamodel.html#object.len for more details.
