API overview

First example

use amplitude::{Amp, Event};
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let amp = Amp::from_env()?; // api key as env variable must be provided
    let mut event1 = Event::new();
    event1
    	.user_id("some user id")
    	.event_type("some event type")
    	.country("UK")
    	.android_id("slmsung-unlimited-hash")
    	.ip4(Some(Ipv4Addr::new(127, 0, 0, 5)))
    	.time(chrono::Utc::now());
    let event2 = Event::from_json(json!(
    	{
            "user_id": "some user id",
            "event_type": "lay on the beach",
            "android_id": "3gfhtey534-647"
        }
    ))?;
    let response = amp.send(vec![event1, event2])?;
    
    Ok(())
}
