Ce que l'on suppose souvent

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

L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.

Contrat

• 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

Fichiers

• Cargo.lock
• Cargo.toml
• csx.json
• src/lib.rs
