ORAO Price Service

This Rust library provides a client for interacting with the ORAO Price Service API. It allows users to fetch price feeds for various assets across different networks.

Features

• Fetch available networks
• Retrieve whitelists for specific networks
• Get latest price feeds for specified assets on a given network

Usage

To use this library in your Rust project, add it to your Cargo.toml:

[dependencies]
orao-price-service = { version = "1.0.2" }

Then, in your Rust code:

use orao_price_service::{PriceService, PriceServiceConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize the PriceService
    let price_service = PriceService::new(
        "https://api.example.com",
        Some(PriceServiceConfig {
            auth_token: Some("your_auth_token".to_string()),
            timeout: Some(5000),
            http_retries: Some(3),
        })
    );

    // Get available networks
    let networks = price_service.get_networks().await?;
    println!("Available networks: {:?}", networks);

    // Get whitelist for a specific network
    let whitelist = price_service.get_whitelist("price-secp256k1").await?;
    println!("price-secp256k1 whitelist: {:?}", whitelist);

    // Get latest price feeds
    let asset_names = vec!["bitcoin".to_string(), "ethereum".to_string()];
    let price_feed = price_service.get_latest_price_feeds("price-secp256k1", &asset_names).await?;
    println!("Latest price feed: {:?}", price_feed);

    Ok(())
}

API Reference

PriceService::new(endpoint: &str, config: Option<PriceServiceConfig>) -> Self

Creates a new instance of PriceService.

PriceService::get_networks() -> Result<Vec<String>>

Retrieves a list of available networks.

PriceService::get_whitelist(network: &str) -> Result<Vec<String>>

Retrieves the whitelist for a specified network.

PriceService::get_latest_price_feeds(network: &str, asset_names: &[String]) -> Result<PriceFeed>

Retrieves the latest price feeds for specified assets on a given network.

Error Handling

All methods return a Result type, allowing for proper error handling. Errors can occur due to network issues, parsing problems, or invalid responses from the API.

Logging

This library uses the tracing crate for logging. You can initialize logging by calling the init_tracing() function provided in the library.
