Struct sc_tracing::ProfilingLayer[][src]

pub struct ProfilingLayer { /* fields omitted */ }
Expand description

Responsible for assigning ids to new spans, which are not re-used.

Implementations

Takes a TracingReceiver and a comma separated list of targets, either with a level: “pallet=trace,frame=debug” or without: “pallet,frame” in which case the level defaults to trace. wasm_tracing indicates whether to enable wasm traces

Allows use of a custom TraceHandler to create a new instance of ProfilingSubscriber. Takes a comma separated list of targets, either with a level, eg: “pallet=trace” or without: “pallet” in which case the level defaults to trace. wasm_tracing indicates whether to enable wasm traces

Registers a new callsite with this layer, returning whether or not the layer is interested in being notified about the callsite, similarly to Subscriber::register_callsite. Read more

Returns true if this layer is interested in a span or event with the given metadata in the current Context, similarly to Subscriber::enabled. Read more

Notifies this layer that a span with the ID span recorded that it follows from the span with the ID follows. Read more

Notifies this layer that a span ID has been cloned, and that the subscriber returned a different ID. Read more

Composes this layer around the given Layer, returning a Layered struct implementing Layer. Read more
