The latter is passed to the [tracing] +/// infrastructure as a span field with the name "NAME". This allows not being distracted by +/// subnames when looking at the trace in <https://ui.perfetto.dev>, but when deeper introspection +/// is needed within a component, it's still possible to view the subnames directly in the UI by +/// selecting a span, clicking on the "NAME" argument on the right, and clicking on "Visualize +/// argument values". +/// ```rust +/// # use rustc_const_eval::enter_trace_span; +/// # type M = rustc_const_eval::const_eval::CompileTimeMachine<'static>; +/// // for example, the first will expand to the second +/// let _span = enter_trace_span!(M, borrow_tracker::on_stack_pop, /* ... */); +/// let _span = enter_trace_span!(M, "borrow_tracker", borrow_tracker = "on_stack_pop", /* ... */); +/// ``` +/// +/// ### `tracing_separate_thread` parameter +/// +/// This macro was introduced to obtain better traces of Miri without impacting release performance. +/// Miri saves traces using the the `tracing_chrome` `tracing::Layer` so that they can be visualized +/// in <https://ui.perfetto.dev>. To instruct `tracing_chrome` to put some spans on a separate trace +/// thread/line than other spans when viewed in <https://ui.perfetto.dev>, you can pass +/// `tracing_separate_thread = tracing::field::Empty` to the tracing macros. This is useful to +/// separate out spans which just indicate the current step or program frame being processed by the +/// interpreter. You should use a value of [tracing::field::Empty] so that other tracing layers +/// (e.g. the logger) will ignore the `tracing_separate_thread` field. For example: +/// ```rust +/// # use rustc_const_eval::enter_trace_span; +/// # type M = rustc_const_eval::const_eval::CompileTimeMachine<'static>; +/// let _span = enter_trace_span!(M, step::eval_statement, tracing_separate_thread = tracing::field::Empty); +/// ``` +/// +/// ### Executing something else when tracing is disabled +/// +/// [crate::interpret::Machine::enter_trace_span] returns [EnteredTraceSpan], on which you can call +/// [EnteredTraceSpan::or_if_tracing_disabled], to e.g. log a line as an alternative to the tracing +/// span for when tracing is disabled. For example: +/// ```rust +/// # use rustc_const_eval::enter_trace_span; +/// # use rustc_const_eval::interpret::EnteredTraceSpan; +/// # type M = rustc_const_eval::const_eval::CompileTimeMachine<'static>; +/// let _span = enter_trace_span!(M, step::eval_statement) +/// .or_if_tracing_disabled(|| tracing::info!("eval_statement")); +/// ``` #[macro_export] macro_rules! enter_trace_span { - ($machine:ident, $($tt:tt)*) => { - $machine::enter_trace_span(|| tracing::info_span!($($tt)*)) - } + ($machine:ty, $name:ident :: $subname:ident $($tt:tt)*) => { + $crate::enter_trace_span!($machine, stringify!($name), $name = %stringify!($subname) $($tt)*) + };
