Struct OptionChainSliceHandle 

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

Boundary-owned wrapper that lets OptionChainSlice cross the cdylib FFI boundary by reference.

The host constructs an instance, hands a *const OptionChainSliceHandle to the plug-in for the duration of the callback, and drops the handle when the call returns. The plug-in only borrows the handle and never owns it.

Implementations

impl OptionChainSliceHandle

pub fn new(slice: OptionChainSlice) -> Self

Wraps slice in a boundary-owned handle.

pub fn chain(&self) -> &OptionChainSlice

Returns a reference to the wrapped option chain slice.

pub fn into_inner(self) -> OptionChainSlice

Consumes the wrapper and returns the inner option chain slice.

Methods from Deref<Target = OptionChainSlice>

pub fn call_count(&self) -> usize

Returns the number of call entries.

pub fn put_count(&self) -> usize

Returns the number of put entries.

pub fn get_call(&self, strike: &Price) -> Option<&OptionStrikeData>

Returns the call data for a given strike price.

pub fn get_put(&self, strike: &Price) -> Option<&OptionStrikeData>

Returns the put data for a given strike price.

pub fn get_call_quote(&self, strike: &Price) -> Option<&QuoteTick>

Returns the call quote for a given strike price.
