drift-rs

drift-rs

Experimental, high performance Rust SDK for building offchain clients for Drift V2 protocol.

Install

# crates.io
drift-rs = "1.0.0-alpha.8"

# build from source
drift-rs = { git = "https://github.com/drift-labs/drift-rs", tag = "v1.0.0-alpha.8" }

Use

use drift_rs::{DriftClient, Wallet};
use solana_sdk::signature::KeyPair;

async fn main() {
    let client = DriftClient::new(
        Context::MainNet,
        RpcClient::new("https://rpc-provider.com"),
        KeyPair::new().into(),
    )
    .await
    .expect("connects");

    /// Subscribe to Ws-based live prices, blockhashes, and oracle updates
    let markets = [MarketId::spot(1), MarketId::perp(0)];
    client.subscribe_markets(&markets).await.unwrap();
}

Setup

Mac (m-series)

Install rosetta and configure Rust toolchain for x86_64

softwareupdate --install-rosetta
# replace `1.84.0` with preferred stable version
rustup install 1.84.0-x86_64-apple-darwin
rustup override set 1.84.0-x86_64-apple-darwin

⚠️ the default toolchain is incompatible due to memory layout differences between solana program (BPF) and aarch64 and will fail at runtime with deserialization errors like: InvalidSize.

Local Development

drift-rs links to the drift program crate via FFI, build from source (default) or dynamically link with a version from drift-ffi-sys

# Build from source (default)
CARGO_DRIFT_FFI_STATIC=1
# Provide a prebuilt drift_ffi_sys lib 
CARGO_DRIFT_FFI_PATH="/path/to/libdrift_ffi_sys"

Development

Release

git tag v<MAJOR.MINOR.PATCH> && git push

Updating IDL types

1. copy the updated IDL to res/drift.json from protocol-v2 branch
2. cargo check
3. commit changes
