Struct Book 

#[non_exhaustive]
pub struct Book {
    pub key: MarketKey,
    pub bids: Vec<Level>,
    pub asks: Vec<Level>,
    pub time: Option<UnixMillis>,
    pub extensions: Extensions,
}

An instrument’s order book at one moment.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: MarketKey

The instrument’s key.

bids: Vec<Level>

Bids, best (highest price) first.

asks: Vec<Level>

Asks, best (lowest price) first.

time: Option<UnixMillis>

When the venue took it.

extensions: Extensions

The venue’s own facts.
