//! Recursion guard for deferred scheduler tracing.

/// Reports whether one scheduler transition should enter the deferred trace ring.
///
/// Disabled tracepoints must impose no capture or wake work. Transitions of
/// any tracing service worker are infrastructure events: recording the
/// scheduler worker directly wakes itself, while recording the pipe or reclaim
/// worker can form a feedback loop through the scheduler worker.
