Auto-generated documentation for ElastiCache type annotations stubs module mypy-boto3-elasticache.

Client

Implicit type annotations

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

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

# ElastiCacheClient usage example

from boto3.session import Session


session = Session()

client = session.client("elasticache")  # (1)
result = client.add_tags_to_resource()  # (2)

1. client: ElastiCacheClient
2. result: TagListMessageTypeDef

# DescribeCacheClustersPaginator usage example

from boto3.session import Session


session = Session()
client = session.client("elasticache")  # (1)

paginator = client.get_paginator("describe_cache_clusters")  # (2)
for item in paginator.paginate(...):
    print(item)  # (3)

1. client: ElastiCacheClient
2. paginator: DescribeCacheClustersPaginator
3. item: CacheClusterMessageTypeDef

# CacheClusterAvailableWaiter usage example

from boto3.session import Session


session = Session()
client = session.client("elasticache")  # (1)

waiter = client.get_waiter("cache_cluster_available")  # (2)
waiter.wait()

1. client: ElastiCacheClient
2. waiter: CacheClusterAvailableWaiter

Explicit type annotations

With boto3-stubs-lite[elasticache] or a standalone mypy_boto3_elasticache package, you have to explicitly specify client: ElastiCacheClient 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.

# ElastiCacheClient usage example with type annotations

from mypy_boto3_elasticache.client import ElastiCacheClient
from mypy_boto3_elasticache.type_defs import TagListMessageTypeDef
from mypy_boto3_elasticache.type_defs import AddTagsToResourceMessageRequestTypeDef


session = Session()

client: ElastiCacheClient = session.client("elasticache")

kwargs: AddTagsToResourceMessageRequestTypeDef = {...}
result: TagListMessageTypeDef = client.add_tags_to_resource(**kwargs)
