/// Trait representing the functions required to collect trace data. /// /// Crates that provide implementations of methods for collecting or recording /// trace data should implement the `Subscriber` interface. This trait is /// intended to represent fundamental primitives for collecting trace events and /// spans — other libraries may offer utility functions and types to make /// subscriber implementations more modular or improve the ergonomics of writing /// subscribers. /// /// A subscriber is responsible for the following: /// - Registering new spans as they are created, and providing them with span /// IDs. Implicitly, this means the subscriber may determine the strategy for /// determining span equality. /// - Recording the attachment of field values and follows-from annotations to /// spans. /// - Filtering spans and events, and determining when those filters must be /// invalidated. /// - Observing spans as they are entered, exited, and closed, and events as /// they occur. /// /// When a span is entered or exited, the subscriber is provided only with the /// [ID] with which it tagged that span when it was created. This means /// that it is up to the subscriber to determine whether and how span _data_ — /// the fields and metadata describing the span — should be stored. The /// [`new_span`] function is called when a new span is created, and at that /// point, the subscriber _may_ choose to store the associated data if it will /// be referenced again. However, if the data has already been recorded and will /// not be needed by the implementations of `enter` and `exit`, the subscriber /// may freely discard that data without allocating space to store it. /// /// ## Overriding default impls /// /// Some trait methods on `Subscriber` have default implementations, either in /// order to reduce the surface area of implementing `Subscriber`, or for /// backward-compatibility reasons. However, many subscribers will likely want /// to override these default implementations. /// /// The following methods are likely of interest: /// /// - [`register_callsite`] is called once for each callsite from which a span /// event may originate, and returns an [`Interest`] value describing whether or /// not the subscriber wishes to see events or spans from that callsite. By /// default, it calls [`enabled`], and returns `Interest::always()` if /// `enabled` returns true, or `Interest::never()` if enabled returns false. /// However, if the subscriber's interest can change dynamically at runtime, /// it may want to override this function to return `Interest::sometimes()`. /// Additionally, subscribers which wish to perform a behaviour once for each /// callsite, such as allocating storage for data related to that callsite, /// can perform it in `register_callsite`. /// /// See also the [documentation on the callsite registry][cs-reg] for details /// on [`register_callsite`]. /// /// - [`event_enabled`] is called once before every call to the [`event`] /// method. This can be used to implement filtering on events once their field /// values are known, but before any processing is done in the `event` method. /// - [`clone_span`] is called every time a span ID is cloned, and [`try_close`] /// is called when a span ID is dropped. By default, these functions do /// nothing. However, they can be used to implement reference counting for /// spans, allowing subscribers to free storage for span data and to determine /// when a span has _closed_ permanently (rather than being exited). /// Subscribers which store per-span data or which need to track span closures /// should override these functions together. /// /// [ID]: super::span::Id /// [`new_span`]: Subscriber::new_span /// [`register_callsite`]: Subscriber::register_callsite /// [`enabled`]: Subscriber::enabled /// [`clone_span`]: Subscriber::clone_span /// [`try_close`]: Subscriber::try_close /// [cs-reg]: crate::callsite#registering-callsites /// [`event`]: Subscriber::event /// [`event_enabled`]: Subscriber::event_enabled pubtrait Subscriber: 'static { /// Invoked when this subscriber becomes a [`Dispatch`]. /// /// ## Avoiding Memory Leaks /// /// `Subscriber`s should not store their own [`Dispatch`].
