Functions ¶
func RegisterAllowedFieldMaskPaths ¶
func RegisterAllowedFieldMaskPaths(rpcFullMethod string, set bool, allPaths []string, allowedPaths ...string)
RegisterAllowedFieldMaskPaths registers the allowed field mask paths for an RPC. Note that all allowed paths and sub-paths must be registered. This function is not safe for concurrent use.
func StreamServerInterceptor ¶
func StreamServerInterceptor() grpc.StreamServerInterceptor
StreamServerInterceptor returns a new streaming server interceptor that validates incoming messages if those incoming messages implement:
(A) ValidateContext(ctx context.Context) error (B) Validate() error (C) ValidateFields(...string) error
If a message implements both, then (A) should call (B).
Invalid messages will be rejected with the error returned from the validator, if that error is a TTN error, or with an `InvalidArgument` if it isn't.
The stage at which invalid messages will be rejected with `InvalidArgument` varies based on the type of the RPC. For `ServerStream` (1:m) requests, it will happen before reaching any userspace handlers. For `ClientStream` (n:1) or `BidiStream` (n:m) RPCs, the messages will be rejected on calls to `stream.Recv()`.
If the RPC's FullPath has a registered list of allowed field mask paths (see RegisterAllowedFieldMaskPaths) and the message implements GetFieldMask() types.FieldMask then the field mask paths are validated according to the registered list.
func UnaryServerInterceptor ¶
func UnaryServerInterceptor() grpc.UnaryServerInterceptor
UnaryServerInterceptor returns a new unary server interceptor that validates incoming messages if those incoming messages implement:
(A) ValidateContext(ctx context.Context) error (B) Validate() error (C) ValidateFields(...string) error
If a message implements both, then (A) should call (B).
Invalid messages will be rejected with the error returned from the validator, if that error is a TTN error, or with an `InvalidArgument` if it isn't.
If the RPC's FullPath has a registered list of allowed field mask paths (see RegisterAllowedFieldMaskPaths) and the message implements GetFieldMask() types.FieldMask then the field mask paths are validated according to the registered list.
