O que costuma-se supor

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

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• 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
