Function logos_rt_list_triple 

pub unsafe extern "C" fn logos_rt_list_triple(
    frame: *mut i64,
    handle_slot: i64,
    vec_slot: i64,
    ptr_slot: i64,
    len_slot: i64,
)

Plant the pin triple for a list handle RETURNED by a self-call (the caller’s view of the callee’s result list).

Safety

frame[handle_slot] must be a live *mut Vec<i64> (registry-owned or a pinned param’s vec).
