defmodule HL7v2.TypedMessage do
@moduledoc """
Typed HL7v2 message with parsed segment structs.
A `TypedMessage` is the result of converting a `RawMessage` through the
`HL7v2.TypedParser`. Known segments (MSH, PID, PV1, etc.) are represented as
their typed struct, Z-segments as `HL7v2.Segment.ZXX` structs, and truly
unknown segments are preserved as raw `{name, fields}` tuples.
