// ## API Overview
// Manages Identity and Access Management (IAM) policies.
// Any implementation of an API that offers access control features
// implements the google.iam.v1.IAMPolicy interface.
// ## Data model
// Access control is applied when a principal (user or service account), takes
// some action on a resource exposed by a service. Resources, identified by
// URI-like names, are the unit of access control specification. Service
// implementations can choose the granularity of access control and the
// supported permissions for their resources.
// For example one database service may allow access control to be
// specified only at the Table level, whereas another might allow access control
// to also be specified at the Column level.
// ## Policy Structure
// See google.iam.v1.Policy
// This is intentionally not a CRUD style API because access control policies
// are created and deleted implicitly with the resources to which they are
// attached.

// If the resource does not exist, this will return an empty set of
// permissions, not a NOT_FOUND error.
// Note: This operation is designed to be used for building permission-aware
// UIs and command-line tools, not for authorization checking. This operation
// may "fail open" without warning.

You can’t perform that action at this time.
