}

Market-by-price implementation with a book depth of 0. Equivalent to MBP-0. The record of the Trades schema.

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.

side: c_char

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.

See Side.

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.

Trait Implementations

impl AsRef<[u8]> for TradeMsg

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TradeMsg

fn clone(&self) -> TradeMsg

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TradeMsg

impl Debug for TradeMsg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TradeMsg

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TradeMsg

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TradeMsg

impl<'a> From<&'a TradeMsg> for RecordRefEnum<'a>

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

Converts to this type from the input type.

impl From<TradeMsg> for RecordEnum

fn from(rec: TradeMsg) -> Self

Converts to this type from the input type.

impl HasRType for TradeMsg

fn has_rtype(rtype: u8) -> bool

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

impl Hash for TradeMsg

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'py> IntoPyObject<'py> for TradeMsg

Available on crate feature python only.

Convert bare TradeMsg to Python by wrapping with UNDEF_TIMESTAMP for ts_out.

type Target = PyAny

The Python output type

type Output = Bound<'py, PyAny>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject(self, py: Python<'py>) -> Result<Self::Output, Self::Error>

Performs the conversion.

impl PartialEq for TradeMsg

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for TradeMsg

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

Tests less than (for self and other) and is used by the < operator.

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Record for TradeMsg

fn header(&self) -> &RecordHeader

Returns a reference to the RecordHeader that comes at the beginning of all record types.

fn raw_index_ts(&self) -> u64

Returns the raw primary timestamp for the record.

fn record_size(&self) -> usize

Returns the size of the record in bytes.

fn rtype(&self) -> Result<RType>

Tries to convert the raw record type into an enum which is useful for exhaustive pattern matching.

fn publisher(&self) -> Result<Publisher>

Tries to convert the raw publisher_id into an enum which is useful for exhaustive pattern matching.
