Crate hl7v2_writer 

HL7 v2 message writer/serializer.

This crate provides serialization functionality for HL7 v2 messages, including:

• Converting message structures to HL7 format
• MLLP framing for network transmission
• JSON serialization (re-exported from hl7v2-json)

Example

use hl7v2_model::{Message, Segment, Field, Rep, Comp, Atom, Delims};
use hl7v2_writer::write;

let message = Message {
    delims: Delims::default(),
    segments: vec![
        Segment {
            id: *b"MSH",
            fields: vec![
                Field::from_text("^~\\&"),  // MSH-2 encoding chars
                Field::from_text("SendingApp"),
            ],
        },
    ],
    charsets: vec![],
};

let bytes = write(&message);
assert!(bytes.starts_with(b"MSH|"));
