FilterId

bevy::log::tracing_subscriber::filter

Struct FilterId 

Source 
pub struct FilterId(/* private fields */);
Expand description

Uniquely identifies an individual Filter instance in the context of a Subscriber.

When adding a Filtered Layer to a Subscriber, the Subscriber generates a FilterId for that Filtered layer. The Filtered layer will then use the generated ID to query whether a particular span was previously enabled by that layer’s Filter.

Note: Currently, the Registry type provided by this crate is the only Subscriber implementation capable of participating in per-layer filtering. Therefore, the FilterId type cannot currently be constructed by code outside of tracing-subscriber. In the future, new APIs will be added to tracing-subscriber to allow non-Registry Subscribers to also participate in per-layer filtering. When those APIs are added, subscribers will be responsible for generating and assigning FilterIds.
