Что обычно предполагают

A subscriber installed with with_default is often assumed to compose with an existing default and propagate to threads spawned inside its closure.

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

Контракт

• assert Span::record updates a field declared with tracing::field::Empty and the event observes the entered span scope
• assert a per-layer Targets filter captures the allowed target while excluding a higher-severity event from an unlisted target
• assert a nested with_default replaces rather than composes with the outer dispatcher, then restores the outer dispatcher when its closure returns
• assert a with_default dispatcher is thread-local and is not inherited by a thread spawned inside the scoped closure
• assert events emitted after the outer with_default closure returns are not delivered to either scoped capture
