pub struct Instrument { /* private fields */ }

Instrument.

Implementations

impl Instrument

pub fn try_new( symbol: &str, base: &Asset, quote: &Asset ) -> Result<Instrument, ParseSymbolError>

Create a new instrument. Return ParseSymbolError if the format of the symbol is not valid.

pub fn spot(base: &Asset, quote: &Asset) -> Instrument

Create a new spot.

pub fn derivative( prefix: &str, symbol: &str, base: &Asset, quote: &Asset ) -> Result<Instrument, ParseSymbolError>

Create a new derivative. Return ParseSymbolError if the prefix is not valid.

Warning

User must make sure that inst1.symbol == inst2.symbol only if inst1.base == inst2.base && inst1.quote == inst2.quote.

pub fn to_reversed_spot(&self) -> Option<Instrument>

Convert to the revsered spot. Return None if it is not a spot.

pub fn try_with_symbol( symbol: Symbol, base: &Asset, quote: &Asset ) -> Result<Instrument, ParseSymbolError>

Create a new instrument with the given symbol. Return ParseSymbolError if the symbol does not match the given base or quote.

Warning

User must make sure that inst1.symbol == inst2.symbol only if inst1.base == inst2.base && inst1.quote == inst2.quote.

pub fn prefer_reversed(self, reversed: bool) -> Instrument

Whether to mark this instrument as a reversed-prefering. Default to false.

pub fn is_prefer_reversed(&self) -> bool

Is this instrument reversed-prefering. Default to false.

pub fn as_symbol(&self) -> &Symbol

Get the symbol.

pub fn is_spot(&self) -> bool

Is spot.

pub fn is_derivative(&self) -> bool

Is derivative.

pub fn base(&self) -> &Asset

Get the base asset.

pub fn quote(&self) -> &Asset

Get the quote asset.

pub fn position<T, P>(&self, position: P) -> Position<T>

where T: PositionNum, P: IntoNaivePosition<T>,

Create a Position with the given position of this instrument.

impl Ord for Instrument

fn cmp(&self, other: &Instrument) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
