Functions

func List 

func List(c *golangsdk.ServiceClient, opts ListOptsBuilder) pagination.Pager

List returns a Pager which allows you to iterate over a collection of l7policies. It accepts a ListOpts struct, which allows you to filter and sort the returned collection for greater efficiency.

Default policy settings return only those l7policies that are owned by the project who submits the request, unless an admin user submits the request.

func ListRules 

func ListRules(c *golangsdk.ServiceClient, policyID string, opts ListRulesOptsBuilder) pagination.Pager

ListRules returns a Pager which allows you to iterate over a collection of rules. It accepts a ListRulesOptsBuilder, which allows you to filter and sort the returned collection for greater efficiency.

Default policy settings return only those rules that are owned by the project who submits the request, unless an admin user submits the request.
