Trait QlogOutput 

pub trait QlogOutput: Send + 'static {
    // Required methods
    fn begin(
        &mut self,
        info: &TraceInfo,
    ) -> impl Future<Output = Result<(), Error>> + Send;

        &mut self,
        event: &QlogEventView<'_>,

    // Provided method
    fn finish(&mut self) -> impl Future<Output = Result<(), Error>> + Send { ... }
}

Available on crate features quic and std only.

Asynchronous storage, invoked by the recording task after event admission. Methods may wait for I/O. Synchronous computation and destruction must finish promptly. An error ends the recorder; partially written records are never retried automatically. One task owns the output exclusively; Send permits executor migration. Implementations remain concrete inside the task, without boxing a future per event.

Required Methods

fn begin( &mut self, info: &TraceInfo, ) -> impl Future<Output = Result<(), Error>> + Send

Initialize output once, before processing events or flush requests.

fn event( &mut self, event: &QlogEventView<'_>, ) -> impl Future<Output = Result<(), Error>> + Send

Write one observation in admission order; an error terminates recording.

fn flush(&mut self) -> impl Future<Output = Result<(), Error>> + Send

Flush buffered output after all earlier admitted commands.

Provided Methods

fn finish(&mut self) -> impl Future<Output = Result<(), Error>> + Send

Finalize output after draining accepted events. Defaults to flushing.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
