-- Publishes a version of your function from the current snapshot of $LATEST. That is, AWS Lambda takes a snapshot of the function code and configuration information from $LATEST and publishes a new version. The code and configuration cannot be modified after publication. For information about the versioning feature, see <http://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html AWS Lambda Function Versioning and Aliases> .

-- | Creates a value of 'PublishVersion' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'pvCodeSha256' - The SHA256 hash of the deployment package you want to publish. This provides validation on the code you are publishing. If you provide this parameter value must match the SHA256 of the $LATEST version for the publication to succeed.
--
-- * 'pvDescription' - The description for the version you are publishing. If not provided, AWS Lambda copies the description from the $LATEST version.
--
-- * 'pvFunctionName' - The Lambda function name. You can specify a function name (for example, @Thumbnail@ ) or you can specify Amazon Resource Name (ARN) of the function (for example, @arn:aws:lambda:us-west-2:account-id:function:ThumbNail@ ). AWS Lambda also allows you to specify a partial ARN (for example, @account-id:Thumbnail@ ). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length.
