Struct GetKeyLastUsageFluentBuilder 

pub struct GetKeyLastUsageFluentBuilder { /* private fields */ }

Fluent builder constructing a request to GetKeyLastUsage.

Returns usage information about the last successful cryptographic operation performed with a specified KMS key, including the operation type, timestamp, and associated CloudTrail event ID.

The TrackingStartDate in the GetKeyLastUsage response indicates the date from which KMS began recording cryptographic activity for a given key. Use this value together with KeyCreationDate to understand the key's usage history:

• If the KeyLastUsage response element is present, the key has been used for a successful cryptographic operation since the TrackingStartDate. The response includes the operation type, timestamp, and associated CloudTrail event ID.

• If the KeyLastUsage response element is empty and KeyCreationDate is on or after TrackingStartDate, the key has not been used for a successful cryptographic operation since it was created.

• If the KeyLastUsage response element is empty and KeyCreationDate is before TrackingStartDate, there is no record of the key being used for a successful cryptographic operation since the TrackingStartDate. However, the key may have been used before tracking began. To determine whether the key was used before the TrackingStartDate, examine your past CloudTrail logs.

For multi-Region KMS keys, primary and replica keys track last usage independently. Each key in a multi-Region key set maintains its own usage information.

The ReEncrypt operation uses two keys: a source key for decryption and a destination key for encryption. Usage information is recorded for both keys independently, each with the CloudTrail event ID from the respective key owner's account.

Do not use GetKeyLastUsage as the sole indicator when scheduling a key for deletion. Instead, first disable the key and monitor CloudTrail for DisabledException entries, as there could be infrequent workflows that are dependent on the key. By looking for this exception, you can identify potential dependencies and workload failures before they occur.

Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.

Required permissions: kms:GetKeyLastUsage (key policy)

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.

Implementations

impl GetKeyLastUsageFluentBuilder

pub fn as_input(&self) -> &GetKeyLastUsageInputBuilder

Access the GetKeyLastUsage as a reference.

pub async fn send( self, ) -> Result<GetKeyLastUsageOutput, SdkError<GetKeyLastUsageError, HttpResponse>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn customize( self, ) -> CustomizableOperation<GetKeyLastUsageOutput, GetKeyLastUsageError, Self>

Consumes this builder, creating a customizable operation that can be modified before being sent.

pub fn key_id(self, input: impl Into<String>) -> Self

Identifies the KMS key to get usage information for. To specify a KMS key, use its key ID or key ARN. Alias names are not supported.

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

pub fn set_key_id(self, input: Option<String>) -> Self

Identifies the KMS key to get usage information for. To specify a KMS key, use its key ID or key ARN. Alias names are not supported.

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

pub fn get_key_id(&self) -> &Option<String>

Identifies the KMS key to get usage information for. To specify a KMS key, use its key ID or key ARN. Alias names are not supported.

Specify the key ID or key ARN of the KMS key.

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

• Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.
