Crate hl7_parser

HL7v2 message parsing in Rust.

Parses the structure of HL7v2 messages, but does not validate the correctness of the messages.

Examples

use hl7_parser::{Message, datetime::TimeStamp};
use std::str::FromStr;

let message =
Message::parse("MSH|^~\\&|foo|bar|baz|quux|20010504094523||ADT^A01|1234|P|2.3|||").unwrap();
let msh = message.segment("MSH").unwrap();
assert_eq!(msh.field(3).unwrap().raw_value(), "foo");

let message_time = msh.field(7).unwrap();
let time: TimeStamp = message_time.raw_value().parse().unwrap();
assert_eq!(time.year, 2001);
assert_eq!(time.month, Some(5));
assert_eq!(time.day, Some(4));

Re-exports

locate

Utilities for locating a cursor within an HL7 message.

message

Functions

parse_message

Parses an HL7 message into a structured form. Equivalent to calling Message::parse(message).
