Struct SyntheticInstrument_API 

pub struct SyntheticInstrument_API(/* private fields */);

C compatible Foreign Function Interface (FFI) for an underlying SyntheticInstrument.

This struct wraps SyntheticInstrument in a way that makes it compatible with C function calls, enabling interaction with SyntheticInstrument in a C environment.

It implements the Deref trait, allowing instances of SyntheticInstrument_API to be dereferenced to SyntheticInstrument, providing access to SyntheticInstruments’s methods without having to manually access the underlying instance.

Methods from Deref<Target = SyntheticInstrument>

pub fn is_valid_formula(&self, formula: &str) -> bool

Returns whether the given formula compiles against this instrument’s components.

pub fn change_formula(&mut self, formula: &str) -> Result<()>

Replaces the derivation formula, recompiling it against the existing components.

Errors

Returns an error if parsing the new formula fails.

pub fn calculate_from_map(&self, inputs: &HashMap<String, f64>) -> Result<Price>

Calculates the price of the synthetic instrument based on component input prices provided as a map.

Errors

Returns an error if formula evaluation fails or a required component price is missing from the input map.

pub fn calculate(&self, inputs: &[f64]) -> Result<Price>

Calculates the price of the synthetic instrument based on the given component input prices provided as an array of f64 values.

Errors

Returns an error if the input length does not match, any input is non-finite, or formula evaluation fails.
