Rust SDK Tutorial
Learn how to use the high-performance Saros DLMM SDK for Rust with this comprehensive guide.
This tutorial will guide you through the process of using the Saros DLMM SDK for Rust. The Rust SDK provides zero-cost abstractions and memory safety for high-performance DeFi applications.
1. Prerequisites
Before starting this tutorial, ensure you have the following:
- Rust and Cargo installed
- Basic knowledge of Rust programming
- Understanding of Solana's account model
- Familiarity with async/await in Rust
- Access to a Solana RPC endpoint
# Install Rust and Cargo
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Add the Saros DLMM SDK to your Cargo.toml
[dependencies]
saros-dlmm-sdk = { path = "../saros-dlmm" }
# Or if using a published version
# saros-dlmm-sdk = "0.1.0"2. Import Modules
Import the necessary modules from the Saros DLMM SDK and Solana SDK.
// Import the necessary modules
use saros_dlmm_sdk::DlmmClient;
use solana_sdk::pubkey::Pubkey;
use anyhow::Result;3. Initialize Client
Create a new DlmmClient instance connected to a Solana RPC endpoint.
// Initialize the DLMM client
#[tokio::main]
async fn main() -> Result<()> {
let client = DlmmClient::new("https://api.devnet.solana.com".to_string())?;
// Your code here
Ok(())
}4. Get All Pools
Retrieve a list of all available DLMM pools.
// Get a list of all available pools
let pools = client.get_all_pools().await?;
println!("Found {} pools", pools.len());
for pool in pools.iter().take(5) {
println!("Pool: {}, TVL: {}", pool.address, pool.tvl);
}5. Get Specific Pool
Retrieve information about a specific DLMM pool by its address.
// Get information about a specific pool
let pool_address = "EwsqJeioGAXE5EdZHj1QvcuvqgVhJDp9729H5wjh28DD".parse::<Pubkey>()?;
let pool = client.get_pool(pool_address).await?;
println!("Pool Address: {}", pool.address);
println!("Token X: {}", pool.token_x);
println!("Token Y: {}", pool.token_y);
println!("TVL: {}", pool.tvl);6. Get Swap Quote
Get a quote for a swap operation to see the expected output amount and price impact.
// Get a quote for a swap operation
let amount = 1_000_000u64; // 1 USDC (6 decimals)
let is_exact_input = true;
let swap_for_y = true;
let pair = pool_address;
let token_base = "C98A4nkJXhpVZNAZdHUA95RpTF3T4whtQubL3YobiUX9".parse::<Pubkey>()?;
let token_quote = "EPjFWdd5AufqSSqeM2qN1zzybapC8G4wEGGkZwyTDt1v".parse::<Pubkey>()?;
let token_base_decimal = 6;
let token_quote_decimal = 6;
let slippage = 0.5; // 0.5% slippage tolerance
let quote = client.get_quote(
amount,
is_exact_input,
swap_for_y,
pair,
token_base,
token_quote,
token_base_decimal,
token_quote_decimal,
slippage
).await?;
println!("Quote: {:?}", quote);7. Execute Swap
Create a transaction for swapping tokens using the quote data.
// Create a transaction for swapping tokens
let transaction = client.swap(
amount,
token_base, // token_mint_x
token_quote, // token_mint_y
quote.other_amount_offset,
is_exact_input,
swap_for_y,
pair,
payer_pubkey // User's wallet pubkey
).await?;
println!("Transaction created: {:?}", transaction);Result<T> for proper error handling.Zero-Cost Abstractions
The Rust SDK provides high-level abstractions without runtime overhead, resulting in performance comparable to hand-written C code.
Memory Safety
Rust's ownership system prevents buffer overflows, null pointer dereferences, and other memory-related bugs at compile time.
Concurrency
Rust's concurrency model makes it easy to write safe, concurrent code without data races.
Interoperability
The Rust SDK can easily integrate with existing Solana programs and other Rust libraries in the ecosystem.
