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.
This is example code to decode and encode a Stellar transaction.
```rust use substratestellarxdr::{xdr, xdr_codec::XdrCodec};
const ENVELOPE: &str = "AAAAAgAAAAC9xFYU1gQJeH4apEfzJkMCsW5DL4GEWRpyVjQHOlWVzgAAAZA\ CGsQoAAQytgAAAAAAAAAAAAAAAgAAAAAAAAADAAAAAVhMUEcAAAAAxxJMrxQQOx9raxDm3\ lINsLvksi7tj1BCQXzWTtqigbgAAAAAAAAAAAbK5N8CprKDAExLQAAAAAAAAAAAAAAAAAA\ AAAMAAAAAAAAAAVhMUEcAAAAAxxJMrxQQOx9raxDm3lINsLvksi7tj1BCQXzWTtqigbgAA\ AAAlV2+xQAEaBMAJiWgAAAAAAAAAAAAAAAAAAAAATpVlc4AAABAaX11e1dGcDkXrFT5s3Q\ N6x3v4kQqJ/1VIjqO00y6OStd70/aYiXR35e4289RvmBTudJ5Q05PaRsD8p1qa17VDQ==";
fn main() { let xdr = base64::decode(ENVELOPE).unwrap(); let envelope = xdr::TransactionEnvelope::fromxdr(&xdr).unwrap(); println!("{:#?}", envelope); asserteq!(xdr, envelope.to_xdr().unwrap()); } ```
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) -> Result<Vec<u8>, WriteStreamError>from_xdr(buffer: &Vec<u8>) -> Result<Self, ReadStreamError>main-types-only: when specified, will only export the main types (Transactions, Operations, etc.)
