rustls and OpenSSL/native-tls

By Default this Crate uses the rustls backend of reqwest, if you need native-tls/openSSL you need to activate the native-tls feature

rustgecko = { version = "*" , features = ["native-tls"] }

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()
        .unwrap();

    let _ = GeckoClient::new_with_custom_client(client, "https://some.url");
}

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() {
    if let Err(err) = GeckoClient::default().exchangerates().await {
        match err.status() {
            Some(StatusCode::TOO_MANY_REQUESTS) => info!("we have to slow down"),
            Some(_) => info!("Something else happened"),
            None => info!("We got an error without a status code"),
        }
    }
}
