Auto-generated documentation for QLDB type annotations stubs module mypy-boto3-qldb.

Client#

Implicit type annotations#

Can be used with boto3-stubs[qldb] package installed.

Write your QLDB code as usual, type checking and code completion should work out of the box.

# QLDBClient usage example

from boto3.session import Session


session = Session()

client = session.client("qldb")  # (1)
result = client.cancel_journal_kinesis_stream()  # (2)
  1. client: QLDBClient
  2. result: CancelJournalKinesisStreamResponseTypeDef

Explicit type annotations#

With boto3-stubs-lite[qldb] or a standalone mypy_boto3_qldb package, you have to explicitly specify client: QLDBClient type annotation.

All other type annotations are optional, as types should be discovered automatically. However, these type annotations can be helpful in your functions and methods.

# QLDBClient usage example with type annotations

from boto3.session import Session

from mypy_boto3_qldb.client import QLDBClient
from mypy_boto3_qldb.type_defs import CancelJournalKinesisStreamResponseTypeDef
from mypy_boto3_qldb.type_defs import CancelJournalKinesisStreamRequestRequestTypeDef


session = Session()

client: QLDBClient = session.client("qldb")

kwargs: CancelJournalKinesisStreamRequestRequestTypeDef = {...}
result: CancelJournalKinesisStreamResponseTypeDef = client.cancel_journal_kinesis_stream(**kwargs)
