🎲 🦀 drand-client-rs

一个简单的 Rust 编写的 drand 客户端实现

功能

• HTTP 传输
• pedersen-bls-chained 方案
• pedersen-bls-unchained 方案
• bls-unchained-on-g1 方案
• bls-unchained-on-g1-rfc9380 方案

示例用法

use drand_client_rs::{new_http_client, DrandClientError};

fn main() -> Result<(), DrandClientError> {
    // first create the client using one of the relays as a `base_url`
    let drand_client = new_http_client("https://api.drand.sh")?;

    // you can fetch the latest random value using `latest_randomness`
    if let Ok(beacon) = drand_client.latest_randomness() {
        println!("the latest round is {}", beacon.round_number);
        println!("the latest randomness is {:?}", beacon.randomness);
    }

    // or a specific round using `randomness`
    if let Ok(beacon) = drand_client.randomness(1) {
        println!("the selected round is {}", beacon.round_number);
        println!("the latest randomness is {:?}", beacon.randomness);
    }

    Ok(())
}
