mypy-boto3-arc-region-switch Type Stubs

1.42.59 · active · verified Sat Apr 11

This library provides type annotations (stubs) for the `boto3` ARCRegionswitch service client, generated with `mypy-boto3-builder`. It enhances development experience by enabling static type checking for `boto3` code. The current version is 1.42.59, and it is actively maintained with frequent updates tied to `boto3` releases and `mypy-boto3-builder` improvements.

Warnings

breaking Starting with `mypy-boto3-builder` version 8.12.0, support for Python 3.8 has been removed. If you are using generated stubs from this builder version or newer, you must upgrade your Python environment to 3.9 or higher.
Fix: Upgrade your Python interpreter to version 3.9 or newer.
gotcha This package (`mypy-boto3-arc-region-switch`) provides only type stubs. For your application to run, you must install the `boto3` library separately. These stubs are used by static analysis tools like `mypy` for type checking, not for runtime execution.
Fix: Ensure `boto3` is installed in your environment: `pip install boto3`.
breaking TypeDef naming conventions were changed in `mypy-boto3-builder` 8.9.0. Specifically, packed method arguments and conflicting TypeDefs might have shorter names or 'Extra' postfix moved. If your code explicitly imports or references generated TypeDefs, these changes could introduce type errors.
Fix: Review your explicit TypeDef imports and references, updating names according to the new conventions (e.g., `CreateDistributionRequestRequestTypeDef` -> `CreateDistributionRequestTypeDef`).
gotcha For the most accurate type checking, ensure that the version of your `mypy-boto3-*` stubs closely matches your installed `boto3` version. Significant version mismatches can lead to incorrect type errors or missed type checks, as service APIs evolve.
Fix: Keep your `mypy-boto3-*` packages and `boto3` up to date and in sync. Consider using a `requirements.txt` with pinned versions.

Install

pip install mypy-boto3-arc-region-switch boto3 Install type stubs and boto3

Imports

ARCRegionswitchClient
```
from mypy_boto3_arc_region_switch.client import ARCRegionswitchClient
```
Type stubs are imported from the specific `mypy-boto3` package, not directly from `boto3`.
ARCRegionswitchServiceName
```
from mypy_boto3_arc_region_switch.type_defs import ARCRegionswitchServiceName
```
Service name literals for type hinting are available in type_defs.

Quickstart

This example demonstrates how to initialize a `boto3` client and use the `ARCRegionswitchClient` type annotation for improved type checking with `mypy`.

import boto3
from mypy_boto3_arc_region_switch.client import ARCRegionswitchClient

def check_arc_config(client: ARCRegionswitchClient) -> None:
    try:
        # Example operation for ARCRegionswitch service
        response = client.get_arc_regionswitch_configuration()
        print(f"ARCRegionswitch configuration: {response}")
    except Exception as e:
        print(f"Error getting ARCRegionswitch configuration: {e}")

if __name__ == '__main__':
    # The actual client must be created from boto3
    # Ensure AWS credentials are configured (e.g., via AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY env vars)
    arc_client: ARCRegionswitchClient = boto3.client(
        'arc-regionswitch', 
        region_name=os.environ.get('AWS_REGION', 'us-east-1')
    )
    check_arc_config(arc_client)
