# markets

Market-specific primitives in Rust. WIP.

```rust
use markets::crypto::{Exchange, Currency, Ticker, Side};

#[derive(Serialize, Deserialize)]
pub struct Trade {
    pub exch: Exchange, // 4-character symbol (bmex, btfx, etc.)
    pub ticker: Ticker, // i.e. btc/usd
    pub side: Side,     // Bid/Ask
    pub price: f64,
    pub size: f64,
    pub time: u64,      // unix nanos
}

let json = r#"
    {
        "exch": "bmex",
        "ticker": "btc_usd",
        "side": "bid",
        "price": 7890.12345,
