Implementations

impl CryptoFuture

pub fn new_checked( instrument_id: InstrumentId, raw_symbol: Symbol, underlying: Currency, quote_currency: Currency, settlement_currency: Currency, is_inverse: bool, activation_ns: UnixNanos, expiration_ns: UnixNanos, price_precision: u8, size_precision: u8, price_increment: Price, size_increment: Quantity, multiplier: Option<Quantity>, lot_size: Option<Quantity>, max_quantity: Option<Quantity>, min_quantity: Option<Quantity>, max_notional: Option<Money>, min_notional: Option<Money>, max_price: Option<Price>, min_price: Option<Price>, margin_init: Option<Decimal>, margin_maint: Option<Decimal>, maker_fee: Option<Decimal>, taker_fee: Option<Decimal>, tick_scheme: Option<Ustr>, info: Option<Params>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> CorrectnessResult<Self>

Creates a new CryptoFuture instance with correctness checking.

Errors

Returns an error if any input validation fails.

Notes

PyO3 requires a Result type for proper error handling and stacktrace printing in Python.

pub fn new( instrument_id: InstrumentId, raw_symbol: Symbol, underlying: Currency, quote_currency: Currency, settlement_currency: Currency, is_inverse: bool, activation_ns: UnixNanos, expiration_ns: UnixNanos, price_precision: u8, size_precision: u8, price_increment: Price, size_increment: Quantity, multiplier: Option<Quantity>, lot_size: Option<Quantity>, max_quantity: Option<Quantity>, min_quantity: Option<Quantity>, max_notional: Option<Money>, min_notional: Option<Money>, max_price: Option<Price>, min_price: Option<Price>, margin_init: Option<Decimal>, margin_maint: Option<Decimal>, maker_fee: Option<Decimal>, taker_fee: Option<Decimal>, tick_scheme: Option<Ustr>, info: Option<Params>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self

Creates a new CryptoFuture instance.

Panics

Panics if any parameter is invalid (see new_checked).

pub fn build_checked( instrument_id: InstrumentId, raw_symbol: Symbol, underlying: Currency, quote_currency: Currency, settlement_currency: Currency, is_inverse: bool, activation_ns: UnixNanos, expiration_ns: UnixNanos, price_precision: u8, size_precision: u8, price_increment: Price, size_increment: Quantity, multiplier: Option<Quantity>, lot_size: Option<Quantity>, max_quantity: Option<Quantity>, min_quantity: Option<Quantity>, max_notional: Option<Money>, min_notional: Option<Money>, max_price: Option<Price>, min_price: Option<Price>, margin_init: Option<Decimal>, margin_maint: Option<Decimal>, maker_fee: Option<Decimal>, taker_fee: Option<Decimal>, tick_scheme: Option<Ustr>, info: Option<Params>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> CorrectnessResult<Self>

Returns a fluent builder for a CryptoFuture instance.

Required fields are enforced at compile time; optional fields can be omitted and default the same way they do in CryptoFuture::new_checked, which the builder calls so the same correctness checks run on build.

Errors

Returns an error if any input validation fails (see CryptoFuture::new_checked).

pub fn builder() -> CryptoFutureBuildCheckedBuilder

Returns a fluent builder for a CryptoFuture instance.

Required fields are enforced at compile time; optional fields can be omitted and default the same way they do in CryptoFuture::new_checked, which the builder calls so the same correctness checks run on build.

Errors

Returns an error if any input validation fails (see CryptoFuture::new_checked).
