Function plugin_call_async 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn plugin_call_async(
    _handle: *mut c_void,
    _type_tag: *const c_char,
    _request: *const u8,
    _request_len: usize,
    _callback: extern "C" fn(context: *mut c_void, request_id: u64, data: *const u8, len: usize, error_code: u32),
    _context: *mut c_void,
) -> u64

Initiate an asynchronous plugin call.

Status

Not yet implemented. This function is reserved for future async API support. Currently returns 0 to indicate the operation is not available.

Planned Behavior

When implemented, this function will:

1. Accept a request and completion callback
2. Submit the request for async processing
3. Return a non-zero request ID for tracking/cancellation
4. Invoke the callback with the response when complete

Safety

When implemented, the following invariants must hold:

• handle must be a valid handle from plugin_init, or null
• type_tag must be a valid null-terminated C string, or null
• request must be valid for request_len bytes, or null if request_len is 0
• callback must remain valid until invoked or the request is cancelled
• context is passed through to the callback unchanged

Returns

Request ID that can be used with plugin_cancel_async, or 0 if not implemented.
