Struct MarketDataFields 

pub struct MarketDataFields(/* private fields */);

Market-data field codes used when subscribing. See bezant_api::GetMdSnapshotRequestQuery for the documented set on the REST side — every code listed there works on the WebSocket too.

Kept as an opaque newtype so we can change the internal representation in a point release without breaking downstream callers.

Implementations

impl MarketDataFields

pub fn default_l1() -> Self

Reasonable default: last price, bid, ask, last size, bid size, ask size.

pub fn from_codes<I, S>(codes: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Build a new MarketDataFields from any iterator of code strings.

pub fn as_slice(&self) -> &[String]

Borrow the underlying field codes — handy when forwarding the same set to multiple subscribes, or serialising for logging.
