Swift MT Message Parser

A Rust library for parsing SWIFT MT (Message Type) messages and extracting their fields. This library focuses purely on parsing and field extraction, not message building or transformation.

Supported Message Types

• MT102: Multiple Customer Credit Transfer
• MT103: Single Customer Credit Transfer
• MT192: Request for Cancellation
• MT195: Queries
• MT196: Answers
• MT197: Copy of a Message
• MT199: Free Format Message
• MT202: General Financial Institution Transfer
• MT940: Customer Statement Message
• MT941: Balance Report Message
• MT942: Interim Transaction Report

Example Usage

use swift_mt_message::{parse_message, MTMessage};

let message_text = "{1:F01BANKDEFFAXXX0123456789}{2:I103BANKDEFFAXXXU3003}{4:\n:20:FT21234567890\n:23B:CRED\n:32A:210315EUR1234567,89\n:50K:JOHN DOE\n:59:JANE SMITH\n-}";
let message = parse_message(message_text)?;

if let MTMessage::MT103(mt103) = message {
    println!("Sender Reference: {}", mt103.sender_reference()?);
    println!("Amount: {:?}", mt103.amount()?);
    println!("Currency: {}", mt103.currency()?);
}
