//! Get a list of role assignments.
//!
//! If no query parameters are specified, then this API will return a list of
//! all role assignments.
//!
//! Since this list is likely to be very long, this API would typically always
//! be used with one of more of the filter queries. Some typical examples are:
//!
//! `GET /v3/role_assignments?user.id={user_id}` would list all role
//! assignments involving the specified user.
//!
//! `GET /v3/role_assignments?scope.project.id={project_id}` would list all
//! role assignments involving the specified project.
//!
//! It is also possible to list all role assignments within a tree of projects:
//! `GET /v3/role_assignments?scope.project.id={project_id}&include_subtree=true`
//! would list all role assignments involving the specified project and all
//! sub-projects. `include_subtree=true` can only be specified in conjunction
//! with `scope.project.id`, specifying it without this will result in an HTTP
//! 400 Bad Request being returned.
//!
//! Each role assignment entity in the collection contains a link to the
//! assignment that gave rise to this entity.
//!
//! The scope section in the list response is extended to allow the
//! representation of role assignments that are inherited to projects.
//!
//! The query filter `scope.OS-INHERIT:inherited_to` can be used to filter
//! based on role assignments that are inherited. The only value of
//! `scope.OS-INHERIT:inherited_to` that is currently supported is `projects`,
//! indicating that this role is inherited to all projects of the owning domain
//! or parent project.
//!
//! If the query parameter `effective` is specified, rather than simply
//! returning a list of role assignments that have been made, the API returns a
//! list of effective assignments at the user, project and domain level, having
//! allowed for the effects of group membership, role inference rules as well
//! as inheritance from the parent domain or project. Since the effects of
//! group membership have already been allowed for, the group role assignment
//! entities themselves will not be returned in the collection. Likewise, since
//! the effects of inheritance have already been allowed for, the role
//! assignment entities themselves that specify the inheritance will also not
//! be returned in the collection. This represents the effective role
//! assignments that would be included in a scoped token. The same set of query
//! parameters can also be used in combination with the `effective` parameter.
//!
//! For example:
//!
//! `GET /v3/role_assignments?user.id={user_id}&effective` would, in other
//! words, answer the question “what can this user actually do?”.
//!
//! `GET /v3/role_assignments?user.id={user_id}&scope.project.id={project_id}&effective`
//! would return the equivalent set of role assignments that would be included
//! in the token response of a project scoped token.
//!
//! An example response for an API call with the query parameter `effective`
//! specified is given below:
//!
//! The entity `links` section of a response using the `effective` query
//! parameter also contains, for entities that are included by virtue of group
//! membership, a url that can be used to access the membership of the group.
//!
//! If the query parameter `include_names` is specified, rather than simply
//! returning the entity IDs in the role assignments, the collection will
//! additionally include the names of the entities. For example:
//!
//! `GET /v3/role_assignments?user.id={user_id}&effective&include_names=true`
//! would return:
//!
//! Relationship:
//! `https://docs.openstack.org/api/openstack-identity/3/rel/role_assignments`
