// Simulate how a set of IAM policies and optionally a resource-based policy works
// with a list of API operations and Amazon Web Services resources to determine the
// policies' effective permissions. The policies are provided as strings. The
// simulation does not perform the API operations; it only checks the authorization
// to determine if the simulated policies allow or deny the operations. You can
// simulate resources that don't exist in your account. If you want to simulate
// existing policies that are attached to an IAM user, group, or role, use
// SimulatePrincipalPolicy instead. Context keys are variables that are maintained
// by Amazon Web Services and its services and which provide details about the
// context of an API query request. You can use the Condition element of an IAM
// policy to evaluate context keys. To get the list of context keys that the
// policies require for correct simulation, use GetContextKeysForCustomPolicy . If
// the output is long, you can use MaxItems and Marker parameters to paginate the
// results. The IAM policy simulator evaluates statements in the identity-based
// policy and the inputs that you provide during simulation. The policy simulator
// results can differ from your live Amazon Web Services environment. We recommend
// that you check your policies against your live Amazon Web Services environment
// after testing using the policy simulator to confirm that you have the desired
// results. For more information about using the policy simulator, see Testing IAM
// policies with the IAM policy simulator (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_testing-policies.html)

ActionNames []string
// A list of policy documents to include in the simulation. Each document is

// character set (through \u00FF )
// - The special characters tab ( \u0009 ), line feed ( \u000A ), and carriage
// return ( \u000D )
//
// This member is required.
PolicyInputList []string
// The ARN of the IAM user that you want to use as the simulated caller of the API
// operations. CallerArn is required if you include a ResourcePolicy so that the
// policy's Principal element has a value to use in evaluating the policy. You can
// specify only the ARN of an IAM user. You cannot specify the ARN of an assumed
// role, federated user, or a service principal.
CallerArn *string
// A list of context keys and corresponding values for the simulation to use.
// Whenever a context key is evaluated in one of the simulated IAM permissions
// policies, the corresponding value is supplied.
ContextEntries []types.ContextEntry
// Use this parameter only when paginating results and only after you receive a
// response indicating that the results are truncated. Set it to the value of the
// Marker element in the response that you received to indicate where the next call
// should start.
Marker *string
// Use this only when paginating results to indicate the maximum number of items
// you want in the response. If additional items exist beyond the maximum you
// specify, the IsTruncated response element is true . If you do not include this
// parameter, the number of items defaults to 100. Note that IAM might return fewer
// results, even when there are more results available. In that case, the
// IsTruncated response element returns true , and Marker contains a value to
// include in the subsequent call that tells the service where to continue from.
MaxItems *int32
// The IAM permissions boundary policy to simulate. The permissions boundary sets
// the maximum permissions that an IAM entity can have. You can input only one
// permissions boundary when you pass a policy to this operation. For more
// information about permissions boundaries, see Permissions boundaries for IAM
// entities (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html)
// in the IAM User Guide. The policy input is specified as a string that contains
// the complete, valid JSON text of a permissions boundary policy. The maximum
// length of the policy document that you can pass in this operation, including
// whitespace, is listed below. To view the maximum character counts of a managed
// policy with no whitespaces, see IAM and STS character quotas (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-quotas.html#reference_iam-quotas-entity-length)

// character set (through \u00FF )
// - The special characters tab ( \u0009 ), line feed ( \u000A ), and carriage
// return ( \u000D )
PermissionsBoundaryPolicyInputList []string
// A list of ARNs of Amazon Web Services resources to include in the simulation.
// If this parameter is not provided, then the value defaults to * (all
// resources). Each API in the ActionNames parameter is evaluated for each
// resource in this list. The simulation determines the access result (allowed or
// denied) of each combination and reports it in the response. You can simulate
// resources that don't exist in your account. The simulation does not
// automatically retrieve policies for the specified resources. If you want to
// include a resource policy in the simulation, then you must include the policy as
// a string in the ResourcePolicy parameter. If you include a ResourcePolicy , then
// it must be applicable to all of the resources included in the simulation or you
// receive an invalid input error. For more information about ARNs, see Amazon
// Resource Names (ARNs) (https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html)
// in the Amazon Web Services General Reference. Simulation of resource-based
// policies isn't supported for IAM roles.
ResourceArns []string
// Specifies the type of simulation to run. Different API operations that support
// resource-based policies require different combinations of resources. By
// specifying the type of simulation to run, you enable the policy simulator to
// enforce the presence of the required resources to ensure reliable simulation
// results. If your simulation does not match one of the following scenarios, then
// you can omit this parameter. The following list shows each of the supported
// scenario values and the resources that you must define to run the simulation.
// Each of the EC2 scenarios requires that you specify instance, image, and
// security group resources. If your scenario includes an EBS volume, then you must
// specify that volume as a resource. If the EC2 scenario includes VPC, then you
// must supply the network interface resource. If it includes an IP subnet, then
// you must specify the subnet resource. For more information on the EC2 scenario
// options, see Supported platforms (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-supported-platforms.html)
// in the Amazon EC2 User Guide.
// - EC2-VPC-InstanceStore instance, image, security group, network interface
// - EC2-VPC-InstanceStore-Subnet instance, image, security group, network
// interface, subnet
// - EC2-VPC-EBS instance, image, security group, network interface, volume
// - EC2-VPC-EBS-Subnet instance, image, security group, network interface,
// subnet, volume
ResourceHandlingOption *string
// An ARN representing the Amazon Web Services account ID that specifies the owner
// of any simulated resource that does not identify its owner in the resource ARN.
// Examples of resource ARNs include an S3 bucket or object. If ResourceOwner is
// specified, it is also used as the account owner of any ResourcePolicy included
// in the simulation. If the ResourceOwner parameter is not specified, then the
// owner of the resources and the resource policy defaults to the account of the
// identity provided in CallerArn . This parameter is required only if you specify
// a resource-based policy and account that owns the resource is different from the
// account that owns the simulated calling user CallerArn . The ARN for an account
// uses the following syntax: arn:aws:iam::AWS-account-ID:root . For example, to
// represent the account with the 112233445566 ID, use the following ARN:
// arn:aws:iam::112233445566-ID:root .
ResourceOwner *string
// A resource-based policy to include in the simulation provided as a string. Each
// resource in the simulation is treated as if it had this policy attached. You can
// include only one resource-based policy in a simulation. The maximum length of
// the policy document that you can pass in this operation, including whitespace,
// is listed below. To view the maximum character counts of a managed policy with
// no whitespaces, see IAM and STS character quotas (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-quotas.html#reference_iam-quotas-entity-length)
