Enum cfn_resource_provider::CfnResponse

This enum represents the response expected by AWS CloudFormation to a custom resource modification request (see CfnRequest). It is serializable into the required JSON form, such that it can be sent to the pre-signed S3 response-URL provided by AWS CloudFormation without further modification.

This type should always be constructed from a CfnRequest using CfnRequest::into_response such that the response-fields are pre-filled with the expected values.

Variants

Success

Indicates that the modification of the custom resource finished successfully.

This can return data which the AWS CloudFormation template can interact with through the use of Fn::GetAtt.

Fields of Success

request_id: String

A unique ID for the request. This response value should be copied verbatim from the request.

logical_resource_id: String

The template developer-chosen name (logical ID) of the custom resource in the AWS CloudFormation template. This response value should be copied verbatim from the request.

stack_id: String

The Amazon Resource Name (ARN) that identifies the stack that contains the custom resource. This response value should be copied verbatim from the request.

physical_resource_id: String

This value should be an identifier unique to the custom resource vendor, and can be up to 1 Kb in size. The value must be a non-empty string and must be identical for all responses for the same resource.

no_echo: Option<bool>

Optional. Indicates whether to mask the output of the custom resource when retrieved by using the Fn::GetAtt function. If set to true, all returned values are masked with asterisks (*****). The default value is false.

data: Option<Value>

Optional. The custom resource provider-defined name-value pairs to send with the response. You can access the values provided here by name in the template with Fn::GetAtt.

Failed

Indicates that the modification of the custom resource failed.

A reason for this failure will be provided.

Fields of Failed

reason: String

Describes the reason for a failure response.

request_id: String

A unique ID for the request. This response value should be copied verbatim from the request.

logical_resource_id: String

The template developer-chosen name (logical ID) of the custom resource in the AWS CloudFormation template. This response value should be copied verbatim from the request.

stack_id: String

The Amazon Resource Name (ARN) that identifies the stack that contains the custom resource. This response value should be copied verbatim from the request.

physical_resource_id: String

This value should be an identifier unique to the custom resource vendor, and can be up to 1 Kb in size. The value must be a non-empty string and must be identical for all responses for the same resource.
