# Messages Library
[](http://www.apache.org/licenses/LICENSE-2.0)
[](CONTRIBUTING.md)
[](https://github.com/Open-Payments/messages/issues)
The library provides tools for parsing, validating, and transforming financial messages, with support for ISO 20022 and FedNow message formats. The library is designed to help developers integrate financial message handling into their Rust applications, using serde for (de)serialization.
---
## Features
- **ISO 20022 Support**: Comprehensive support for key ISO 20022 payment message types.
- **FedNow Message**: Full support for FedNow message formats.
- **(De)serialization**: Using serde for easy conversion between XML and JSON.
- **Extensibility**: Easily extendable to support additional message types or custom formats.
---
## Getting Started
### Prerequisites
You’ll need the following installed to build and use this library:
- [Rust](https://www.rust-lang.org/tools/install) (latest stable version)
- [Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html) (Rust package manager)
### Installation
Add the following to your `Cargo.toml` to start using the library in your Rust project:
```toml
[dependencies]
# This dependency includes support for the entire ISO 20022 message formats.
# The "payments" feature enables various ISO 20022 message categories, such as pacs, pain, camt, etc.
# If you only need specific message types, you can enable just those features (e.g., "pacs", "pain").
open-payments-iso20022 = { version = "1.0.1", features = ["payments"] }
# This dependency provides support for the FedNow message formats.
# You get full support for parsing and serializing FedNow messages out of the box.
open-payments-fednow = "1.0.1"
```
### Features
The ISO20022 message library `open-payments-iso20022` provides several features to allow you to include only the message types relevant to your use case. Here’s a breakdown of the available features:
```toml
[features]
default = ["head"] # Default feature, includes the basic header message.
iso20022 = ["payments"] # Enables all payment-related ISO 20022 messages.
payments = ["acmt", "admi", "auth", "camt", "head", "pacs", "pain", "reda", "remt"] # Includes all payments-related ISO 20022 message types.
# Individual ISO 20022 message modules:
acmt = ["open-payments-iso20022-acmt"] # Account Management messages
admi = ["open-payments-iso20022-admi"] # Administrative messages
auth = ["open-payments-iso20022-auth"] # Authorization messages
camt = ["open-payments-iso20022-camt"] # Cash Management messages
head = ["open-payments-iso20022-head"] # Basic Header messages (default)
pacs = ["open-payments-iso20022-pacs"] # Payment Clearing and Settlement messages
pain = ["open-payments-iso20022-pain"] # Payment Initiation messages
reda = ["open-payments-iso20022-reda"] # Reference Data messages
remt = ["open-payments-iso20022-remt"] # Remittance Advice messages
```
By configuring the features, you can optimize the library for your specific message requirements, minimizing unnecessary dependencies.
### Usage
**Example: Creating an ISO 20022 Message Object**
```rust
use open_payments_iso20022::document::Document;
use open_payments_iso20022_admi::admi_002_001_01::Admi00200101;
fn main() {
let doc = Document::Admi00200101(Box::new(Admi00200101::default()));
println!("{:?}", doc)
}
```
**Example: Creating a FedNow Message Object**
Similarly, here’s an example of how to create a FedNow message object:
```rust
use open_payments_fednow::document::Document;
use open_payments_fednow::iso::pacs_008_001_08::FIToFICustomerCreditTransferV08;
fn main() {
let doc = Document::FIToFICustomerCreditTransferV08(Box::new(FIToFICustomerCreditTransferV08::default()));
println!("{:?}", doc)
}
```
### Supported Messages
The library supports a variety of financial message formats from both ISO 20022 and FedNow, covering key areas of the payment lifecycle.
#### ISO 20022 Messages
- **pacs**: Payment Clearing and Settlement
- **pain**: Payment Initiation
- **admi**: Administrative messages
- **auth**: Authorization messages
- **camt**: Cash Management
- **reda**: Reference Data
- **remt**: Remittance Advice
- **acmt**: Account Management
- **head**: Header messages
#### FedNow Messages
- **Customer Credit Transfer**
- **Payment Status Report**
- **Payment Return**
