Function attach_span 

pub unsafe fn attach_span<O: IsA<Object>>(object: &O, span: Span)

Attach a span to a GStreamer object.

All events logged for this object and its children will have the provided span as the parent. This can be used to associate extra context to a pipeline for example.

Safety

This function is racy and must not be called when an element or any of its children may want to emit a log message. It is generally safe to call this function during early initialization of a pipeline, or when the code in calling this has exclusive control of the elements involved.

Examples

gst::init().unwrap();

let pipeline = gst::Pipeline::new();
let gst_log_span = tracing::info_span!(
    parent: None,
    "gst log",
    pipeline = "encoding",
    id = 42,
);
unsafe {
    gst_tracing::attach_span(&pipeline, gst_log_span);
}
