Type Definitions
================

.. module:: microscopic_gating.types

This module defines type aliases and protocols used throughout the package.

Type Aliases
------------

.. autodata:: ArrayLike
   :annotation:

Protocols
---------

.. autoclass:: Isotherm
   :members:
   :member-order: bysource

.. autoclass:: ContactProbability
   :members:
   :member-order: bysource

Data Classes
------------

.. autoclass:: SitePairCount
   :members: M, N_acc
   :exclude-members: N_pair
   :member-order: bysource
   :show-inheritance:

Type Hierarchy
--------------

The type system is designed for flexibility:

- **ArrayLike** - Any array-like input (numpy arrays, lists, scalars)
- **Isotherm** - Protocol for any object with a ``theta(phi)`` method
- **ContactProbability** - Protocol for geometry factors

This allows easy extension with custom isotherms or geometry models.
