docs: // SetVaultAccessPolicy API operation for Amazon Glacier.
  //
  // This operation configures an access policy for a vault and will overwrite
  // an existing policy. To configure a vault access policy, send a PUT request
  // to the access-policy subresource of the vault. An access policy is specific
  // to a vault and is also called a vault subresource. You can set one access
  // policy per vault and the policy can be up to 20 KB in size. For more information
  // about vault access policies, see Amazon Glacier Access Control with Vault
  // Access Policies (http://docs.aws.amazon.com/amazonglacier/latest/dev/vault-access-policy.html).
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for Amazon Glacier's
  // API operation SetVaultAccessPolicy for usage and error information.
  //
