Function moq_error_protocol 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn moq_error_protocol(
    out: *mut moq_protocol_error,
) -> i32

Structured protocol details for the most recent failed call on the calling thread.

When that failure was a session close or stream reset, writes the scope, verbatim wire code, and recognized kind into out and returns 0. Returns a negative code (and leaves out untouched) when the last error was not a protocol failure (transport, not-found, a bad handle, …). Do not parse moq_error for this.

The values are only meaningful after a call returned a negative code; check the code first. Same lifetime as moq_error: overwritten by the next libmoq call on this thread. Errors delivered through status callbacks are recorded before the callback runs, so read this from inside the callback.

Safety

• The caller must ensure that out is a valid pointer to a moq_protocol_error.
