Function orderbook_deltas_new 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn orderbook_deltas_new(
    instrument_id: InstrumentId,
    deltas: &CVec,
) -> *mut OrderBookDeltas

Creates a new OrderBookDeltas instance from a CVec of OrderBookDeltaFfi.

The data is cloned into Rust-managed memory and remains owned by the caller.

Returns an owning pointer to the heap-allocated OrderBookDeltas which the caller must eventually pass to orderbook_deltas_drop.

Safety

deltas must describe initialized OrderBookDeltaFfi values that remain valid and immutable for the duration of this call. The caller remains responsible for deallocating its buffer.
