A coder/decoder of Stellar XDR types

This repository generates a Rust decoder and encoder of all XDR types used in Stellar. The code is generated via the Substrate Stellar XDR generator.

Usage

This is example code to decode and encode a Stellar transaction.

use substrate_stellar_xdr::{xdr, xdr_codec::XdrCodec};

const ENVELOPE: &str =
    "AAAAAgAAAAC9xFYU1gQJeH4apEfzJkMCsW5DL4GEWRpyVjQHOlWVzgAAAZA\
    CGsQoAAQytgAAAAAAAAAAAAAAAgAAAAAAAAADAAAAAVhMUEcAAAAAxxJMrxQQOx9raxDm3\

    N6x3v4kQqJ/1VIjqO00y6OStd70/aYiXR35e4289RvmBTudJ5Q05PaRsD8p1qa17VDQ==";

fn main() {
    let xdr = base64::decode(ENVELOPE).unwrap();
    let envelope = xdr::TransactionEnvelope::from_xdr(&xdr).unwrap();
    println!("{:#?}", envelope);
    assert_eq!(xdr, envelope.to_xdr());
}

All Stellar XDR types are defined in the module xdr. Each type implements the xdr_codex::XdrCodec trait, which defines the following two useful methods:

• fn to_xdr(&self) -> Vec<u8>
• from_xdr(buffer: &Vec<u8>) -> Result<Self, ReadStreamError>

Features

• main-types-only: when specified, will only export the main types (Transactions, Operations, etc.)
