coingecko-rs's Introduction

CoinGecko Rust

Rust crate for interacting with the CoinGecko v3 API.

At this time, async support is provided by isahc. I would like to have generic HTTP client support, but surf is currently unsuitable for user in a library due to it's error type not being compatible with std::Error. The isahc crate is suitable for now and ideal on Linux systems since it takes advantage of the system libcurl for HTTPS support.

Supported APIs

/ping
/simple/price
/coins/list
/coins/{id}
/coins/markets

Example

use coingecko::{Client, SimplePriceReq};

pub fn main() {
    smol::block_on(async {
        let http = isahc::HttpClient::new().unwrap();

        let client = Client::new(http);

        let req = SimplePriceReq::new("ethereum,algorand,tezos".into(), "usd".into())
            .include_market_cap()
            .include_24hr_vol()
            .include_24hr_change()
            .include_last_updated_at();

        println!("{:#?}", client.simple_price(req).await);
    })
}
