Consolidated market by price implementation with a known book depth of 1. The record of the Cbbo schema.

Fields

hd: RecordHeader

The common header.

price: i64

The order price expressed as a signed integer where every 1 unit corresponds to 1e-9, i.e. 1/1,000,000,000 or 0.000000001.

size: u32

The order quantity.

action: c_char

The event action. Can be Add, Cancel, Modify, cleaR, or Trade.

side: c_char

The side that initiates the event. Can be Ask for a sell order (or sell aggressor in a trade), Bid for a buy order (or buy aggressor in a trade), or None where no side is specified by the original source.

flags: u8

A combination of packet end with matching engine status. See enums::flags for possible values.

ts_recv: u64

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

ts_in_delta: i32

The delta of ts_recv - ts_exchange_send, max 2 seconds.

sequence: u32

The message sequence number assigned at the venue.

levels: [ConsolidatedBidAskPair; 1]

The top of the order book.

Implementations

impl CbboMsg

pub fn default_for_schema(schema: Schema) -> Self

Creates a new default CbboMsg for the given schema.

impl CbboMsg

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

Tries to convert the raw side to an enum.

Errors

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

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

Tries to convert the raw event action to an enum.

Errors

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

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

Parses the raw 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 raw ts_in_delta—the delta of ts_recv - ts_exchange_send—into a duration.

Trait Implementations

fn from(rec: &'a CbboMsg) -> Self

Converts to this type from the input type.

impl From<CbboMsg> for RecordEnum

fn from(rec: CbboMsg) -> Self

Converts to this type from the input type.

impl HasRType for CbboMsg

fn has_rtype(rtype: u8) -> bool

Returns true if rtype matches the value associated with the implementing type.

impl Hash for CbboMsg

impl PartialEq for CbboMsg

fn eq(&self, other: &CbboMsg) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CbboMsg

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
