DEPRACATED

This crate is depracated, it is now part of the Substrate Stellar SDK.

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.

```rust use substratestellarxdr::{xdr, xdr_codec::XdrCodec};

const ENVELOPE: &str = "AAAAAgAAAAC9xFYU1gQJeH4apEfzJkMCsW5DL4GEWRpyVjQHOlWVzgAAAZA\ CGsQoAAQytgAAAAAAAAAAAAAAAgAAAAAAAAADAAAAAVhMUEcAAAAAxxJMrxQQOx9raxDm3\ lINsLvksi7tj1BCQXzWTtqigbgAAAAAAAAAAAbK5N8CprKDAExLQAAAAAAAAAAAAAAAAAA\ AAAMAAAAAAAAAAVhMUEcAAAAAxxJMrxQQOx9raxDm3lINsLvksi7tj1BCQXzWTtqigbgAA\ AAAlV2+xQAEaBMAJiWgAAAAAAAAAAAAAAAAAAAAATpVlc4AAABAaX11e1dGcDkXrFT5s3Q\ N6x3v4kQqJ/1VIjqO00y6OStd70/aYiXR35e4289RvmBTudJ5Q05PaRsD8p1qa17VDQ==";

fn main() { let envelope = xdr::TransactionEnvelope::frombase64xdr(ENVELOPE).unwrap(); println!("{:#?}", envelope); asserteq!(xdr, envelope.toxdr()); } ```

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>: encode as binary XDR
• fn to_base64_xdr(&self) -> Vec<u8>: encode as XDR, afterwards encode result as base64
• from_xdr<T: AsRef<[u8]>>(input: T) -> Result<Self, DecodeError>: decode binary XDR
• from_base64_xdr<T: AsRef<[u8]>>(input: T) -> Result<Self, DecodeError>: decode as base64, then decode result as XDR

Features

• all-types: when specified, will generate all types – otherwise only those types are generated that are in the dependency tree of the types TransactionEnvelope, TransactionResult, TransactionMeta, EnvelopeType and TransactionSignaturePayload
