"""Helpers for use with type annotation.
|
|
|
|
Use the empty classes in this module when annotating the types of Pyrsistent
|
|
objects, instead of using the actual collection class.
|
|
|
|
For example,
|
|
|
|
from pyrsistent import pvector
|
|
from pyrsistent.typing import PVector
|
|
|
|
myvector: PVector[str] = pvector(['a', 'b', 'c'])
|
|
|
|
