Struct TelemetryCore 

pub struct TelemetryCore;

Available on crate feature dial9 only.

Entry point for creating a telemetry session decoupled from any tokio runtime.

Use TelemetryCore::builder() to configure the session, then call TelemetryGuard::trace_runtime to attach one or more runtimes.

let writer = RotatingWriter::single_file("/tmp/trace.bin")?;
let guard = TelemetryCore::builder()
    .writer(writer)
    .build()?;
guard.enable();

let mut builder = tokio::runtime::Builder::new_multi_thread();
builder.worker_threads(4).enable_all();
let (runtime, handle) = guard.trace_runtime("main").build(builder)?;
