L1 ConstructAWS::Lambda::Version

CfnVersion

The `AWS::Lambda::Version` resource creates a [version](https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html) from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

Import

import { CfnVersion } from 'aws-cdk-lib/aws-lambda';

Or use the module namespace:

import * as lambda from 'aws-cdk-lib/aws-lambda';
// lambda.CfnVersion
