View Source Avrogen.Avro.Types.Logical.DurationString (avrogen v1.0.0)
This type does not conform to the Avro duration specification. The Avro duration specification represents a duration with three unsigned integers: months, days, and milliseconds.
This is useful when the Avro value is stored as an ISO 8601 duration string,
but the generated Elixir type should be Duration.
