Constructs a span at the trace level.

Fields and attributes are set using the same syntax as the span! macro.

See the top-level documentation for details on the syntax accepted by this macro.

Examples

trace_span!("my_span");
// is equivalent to:
span!(Level::TRACE, "my_span");

let span = trace_span!("my span");
span.in_scope(|| {
    // do work inside the span...
});
