SignerDataPlaneClient

ListSigningJobsResponseTypeDef
✓ from mypy_boto3_signer_data.type_defs import ListSigningJobsResponseTypeDef
Used for type-hinting responses from AWS service calls.
This quickstart demonstrates how to use `mypy-boto3-signer-data` for type-hinting a `boto3` SignerDataPlane client and its response. The `TYPE_CHECKING` guard ensures that `mypy-boto3` is only a development dependency. It retrieves and prints a list of signing jobs.
import boto3
from typing import TYPE_CHECKING
import os
if TYPE_CHECKING:
from mypy_boto3_signer_data.client import SignerDataPlaneClient
from mypy_boto3_signer_data.type_defs import ListSigningJobsResponseTypeDef
def list_signer_jobs() -> ListSigningJobsResponseTypeDef:
"""Lists AWS Signer Data Plane signing jobs."""
# Ensure AWS credentials are configured (e.g., via environment variables, ~/.aws/credentials)
# This example uses placeholder region and credentials for demonstration.
# In a real application, boto3 automatically picks up credentials.
region_name = os.environ.get('AWS_DEFAULT_REGION', 'us-east-1')
client: SignerDataPlaneClient = boto3.client("signer-data", region_name=region_name)
response = client.list_signing_jobs(
maxResults=10 # Limit results for example
)
print("Successfully listed Signer Data Plane jobs.")
for job in response.get("jobs", []):
print(f" Job ID: {job.get('jobId')}, Status: {job.get('status')}")
return response

Known issues
breakingSupport for Python 3.8 has been removed in `mypy-boto3-builder` version 8.12.0, affecting all generated packages including `mypy-boto3-signer-data`. Projects using Python 3.8 or older will encounter compatibility issues.fixUpgrade your Python environment to version 3.9 or newer.
affects: mypy-boto3-builder >= 8.12.0
breakingGenerated `TypeDef` names may have changed in `mypy-boto3-builder` version 8.9.0. Specifically, packed method arguments use shorter names (e.g., `CreateDistributionRequestRequestTypeDef` to `CreateDistributionRequestTypeDef`), and conflicting `Extra` postfixes were moved (e.g., `CreateDistributionExtraRequestTypeDef` to `CreateDistributionRequestExtraTypeDef`).fixReview your code for any explicit imports or usage of `TypeDef` names, and update them according to the new naming conventions. Refer to the specific service's `type_defs.pyi` for exact `TypeDef` names.
affects: mypy-boto3-builder >= 8.9.0
gotcha`mypy-boto3-signer-data` provides only type stubs and does not include the actual `boto3` runtime. Your application must have `boto3` installed to function at runtime. The type stubs are solely for static analysis.fixAlways ensure `boto3` is installed in your runtime environment (e.g., `pip install boto3`).
affects: All
gotcha`mypy-boto3` uses a separate package for each AWS service. If you need type hints for multiple services (e.g., S3 and SignerDataPlane), you must install each corresponding stub package (e.g., `mypy-boto3-s3` and `mypy-boto3-signer-data`).fixInstall each `mypy-boto3-SERVICE_NAME` package individually for the services you use.
affects: All
gotchaTo prevent `mypy-boto3-*` packages from becoming runtime dependencies, it is best practice to wrap all imports of types from these libraries within a `if typing.TYPE_CHECKING:` block. This ensures they are only used during static analysis.fixEnclose type stub imports like `from mypy_boto3_signer_data.client import SignerDataPlaneClient` within `if TYPE_CHECKING:` conditional blocks.
affects: All
gotchaFor large projects or when using PyCharm, performance issues with Literal overloads in type stubs (issue PY-40997) might lead to high CPU usage or slow IDE performance.fixConsider installing the `boto3-stubs-lite` version (e.g., `pip install 'boto3-stubs-lite[signer-data]'`) if available for your service, which is more RAM-friendly but requires explicit type annotations. Alternatively, disable PyCharm's internal type checker and use `mypy` or `pyright` instead for type checking.
affects: All
deprecatedOccasionally, specific AWS services may be renamed or deprecated within the `boto3` ecosystem (e.g., `sms-voice` was replaced by `pinpoint-sms-voice` in `mypy-boto3-builder` 8.11.0). While this stub is for `signer-data`, always refer to official AWS `boto3` documentation for service names and changes, as they might eventually affect the stub package name or availability.fixRefer to official AWS `boto3` documentation for service names and changes. If a service is renamed, update your `boto3.client()` calls and stub imports accordingly.
