CoinGecko API Client for Rust

Simple API Client for CoinGecko written in Rust

Available endpoint

Refer to CoinGecko official API

More api Endpoints than listed here will be supported in the Future. As soon as I start working on additional Endpoints the Table will be updated.

Shortcut Methods

Some Methods with a lot of boolean Flags have a shorter Version i.E "simple_price_short" for if you just want to retrieve Some Data and leave the Rest of the Params as their Default.

Usage

use rustgecko::client::GeckoClient;

fn main() {
    let client = GeckoClient::default();
}

In a Production Setting or when you have a Coingecko Subscription you might want to supply your own Client with Credentials or with any other additional configuration.

use rustgecko::client::GeckoClient;

fn main() {
    use reqwest::header;
    let mut headers = header::HeaderMap::new();

    // Consider marking security-sensitive headers with `set_sensitive`.
    let mut auth_value = header::HeaderValue::from_static("secret");
    auth_value.set_sensitive(true);
    headers.insert("x-cg-pro-api-key", auth_value);

    // get a client builder
    let client = reqwest::Client::builder()
        .default_headers(headers)
        .build()?;

    let _ = GeckoClient::new_with_custome_client(client);
}

Error Handling

Every 4XX Response is turned into an error of type reqwest::Error and propagated up the call chain.
For handling reqwest errors reference the Docs -> https://docs.rs/reqwest/0.7.2/reqwest/struct.Error.html

async fn main(){
    match client.coins_list().await {
        Ok(response) => {
            println!("We got a response :)");
        }
        Err(err) => {
            println!("Oh no we got a 4XX Response or some other kind of reqwest error :(");
        }
    }
}
