Fields

hd: RecordHeader

The common header.

price: i64

The trade price where every 1 unit corresponds to 1e-9, i.e. 1/1,000,000,000 or 0.000000001.

See Prices.

size: u32

The order quantity.

action: c_char

The event action. Always Trade in the trades schema.

See Action.

The side that initiates the trade. Can be Ask for a sell aggressor in a trade, Bid for a buy aggressor in a trade, or None where no side is specified.

flags: FlagSet

A bit field indicating event end, message characteristics, and data quality. See flags for possible values.

depth: u8

The book level where the update event occurred.

ts_recv: u64

The capture-server-received timestamp expressed as the number of nanoseconds since the UNIX epoch.

See ts_recv.

ts_in_delta: i32

The matching-engine-sending timestamp expressed as the number of nanoseconds before ts_recv.

See ts_in_delta.

sequence: u32

The message sequence number assigned at the venue.

Implementations

impl TradeMsg

pub fn price_f64(&self) -> f64

Converts the price to a floating point.

UNDEF_PRICE will be converted to NaN.

This may introduce floating-point error.

pub fn action(&self) -> Result<Action>

Parses the action into an enum.

Errors

This function returns an error if the action field does not contain a valid Action.

pub fn side(&self) -> Result<Side>

Parses the side into an enum.

Errors

This function returns an error if the side field does not contain a valid Side.

pub fn ts_recv(&self) -> Option<OffsetDateTime>

Parses the capture-server-received timestamp into a datetime. Returns None if ts_recv contains the sentinel for a null timestamp.

pub fn ts_in_delta(&self) -> Duration

Parses the difference between ts_recv and the matching-engine-sending timestamp into a duration.
