Struct sc_tracing::ProfilingLayer
source · pub struct ProfilingLayer { /* private fields */ }
Expand description
Responsible for assigning ids to new spans, which are not re-used.
Implementations§
source§impl ProfilingLayer
impl ProfilingLayer
sourcepub fn new(receiver: TracingReceiver, targets: &str) -> Self
pub fn new(receiver: TracingReceiver, targets: &str) -> Self
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
sourcepub fn new_with_handler(
trace_handler: Box<dyn TraceHandler>,
targets: &str
) -> Self
pub fn new_with_handler( trace_handler: Box<dyn TraceHandler>, targets: &str ) -> Self
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
sourcepub fn add_handler(&mut self, trace_handler: Box<dyn TraceHandler>)
pub fn add_handler(&mut self, trace_handler: Box<dyn TraceHandler>)
Attach additional handlers to allow handling of custom events/spans.

the layer is interested in being notified about the callsite, similarly
to
Subscriber::register_callsite
. Read moresource§fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool
Returns
true

given metadata
in the current Context
, similarly to
Subscriber::enabled
