    public static final class Mixin.Builder
extends GeneratedMessageV3.Builder<Mixin.Builder>
implements MixinOrBuilder
     Declares an API Interface to be included in this interface. The including
 interface must redeclare all the methods from the included interface, but
 documentation and options are inherited as follows:
 - If after comment and whitespace stripping, the documentation
   string of the redeclared method is empty, it will be inherited
   from the original method.
 - Each annotation belonging to the service config (http,
   visibility) which is not set in the redeclared method will be
   inherited.
 - If an http annotation is inherited, the path pattern will be
   modified as follows. Any version prefix will be replaced by the
   version of the including interface plus the [root][] path if
   specified.
 Example of a simple mixin:
     package google.acl.v1;
     service AccessControl {
       // Get the underlying ACL object.
       rpc GetAcl(GetAclRequest) returns (Acl) {
         option (google.api.http).get = "/v1/{resource=**}:getAcl";
       }
     }
     package google.storage.v2;
     service Storage {
       rpc GetAcl(GetAclRequest) returns (Acl);
       // Get a data record.
       rpc GetData(GetDataRequest) returns (Data) {
         option (google.api.http).get = "/v2/{resource=**}";
       }
     }
 Example of a mixin configuration:
     apis:
     - name: google.storage.v2.Storage
       mixins:
       - name: google.acl.v1.AccessControl
 The mixin construct implies that all methods in `AccessControl` are
 also declared with same name and request/response types in
 `Storage`. A documentation generator or annotation processor will
 see the effective `Storage.GetAcl` method after inherting
 documentation and annotations as follows:
     service Storage {
       // Get the underlying ACL object.
       rpc GetAcl(GetAclRequest) returns (Acl) {
         option (google.api.http).get = "/v2/{resource=**}:getAcl";
       }
       ...
     }
 Note how the version in the path pattern changed from `v1` to `v2`.
 If the `root` field in the mixin is specified, it should be a
 relative path under which inherited HTTP paths are placed. Example:
     apis:
     - name: google.storage.v2.Storage
       mixins:
       - name: google.acl.v1.AccessControl
         root: acls
 This implies the following inherited HTTP annotation:
     service Storage {
       // Get the underlying ACL object.
       rpc GetAcl(GetAclRequest) returns (Acl) {
         option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
       }
       ...
     }
