# py2http.types

This module defines several type aliases and constants related to function parameters and signatures.

The `WriteOpResult` TypedDict represents the result of a write operation, with keys for the success status (`ok`), number of items affected (`n`), and identifiers (`ids`) of the affected items.

The `ParameterKind` constant represents the type of a Parameter, specifically `Parameter.POSITIONAL_OR_KEYWORD`.

The `Params` alias is used to represent an Iterable of Parameter objects, while `HasParams` is a union type that can represent various structures that contain Parameter objects, such as Iterable, Mapping, Signature, or Callable.

Additionally, shorthand constants are defined for the different kinds of parameters:

- `PK` for `Parameter.POSITIONAL_OR_KEYWORD`
- `VP` and `VK` for `Parameter.VAR_POSITIONAL` and `Parameter.VAR_KEYWORD` respectively
- `PO` and `KO` for `Parameter.POSITIONAL_ONLY` and `Parameter.KEYWORD_ONLY` respectively
- `var_param_kinds` is a set containing `VP` and `VK` for easy access to variable parameter kinds.

This module provides a convenient way to work with function parameters and signatures in Python.
