Function rust_future_poll

pub unsafe fn rust_future_poll<ReturnType>(
    handle: RustFutureHandle,
    callback: extern "C" fn(_: *const (), _: RustFuturePoll),
    data: *const (),
)

Poll a Rust future

When the future is ready to progress the continuation will be called with the data value and a RustFuturePoll value. For each rust_future_poll call the continuation will be called exactly once.

Safety

The RustFutureHandle must not previously have been passed to rust_future_free
