Fields

context: *mut c_void

An opaque context object retained by this library. The library will pass this back into all callbacks. The memory pointed to by context must last until block_server_delete is called.

start_thread: unsafe extern "C" fn(context: *mut c_void, arg: *const c_void)

Starts a thread. The implementation must call block_server_thread on this newly created thread, providing arg. The implementation must then call block_server_thread_delete after block_server_thread returns (but before block_server_delete is called).

on_new_session: unsafe extern "C" fn(context: *mut c_void, session: *const Session)

Notifies the implementation of a new session. The implementation must call block_server_session_run on a separate thread, and must call block_server_session_release after block_server_session_run (but before block_server_delete is called).

on_requests: unsafe extern "C" fn(context: *mut c_void, requests: *mut Request, request_count: usize)

Submits a batch of requests to be handled by the implementation. The implementation must not retain references to requests after it returns. The implementation must ensure that block_server_send_reply is called exactly once with the request ID of each entry in requests, regardless of its status; this call can be asynchronous but must occur before block_server_delete is called.

log: unsafe extern "C" fn(context: *mut c_void, message: *const c_char, message_len: usize)

Logs message to the implementation’s logger. The implementation must not retain references to message.
