type MsgDefinition = [FieldDefinition]

ROS message is a list of fields

type FieldName = Text

Field name is text encoded

type Field = (FieldType, FieldName)

Field is a pair of name - value

Time describing

type ROSDuration = (Int32, Int32)

ROSDuration is a tuple of (seconds, nanoseconds)

type ROSTime = (Word32, Word32)

ROSTime is a tuple of (seconds, nanoseconds)
