Expand description

Extension trait for self-profiling purposes: allows to record spans within a generic activity’s event arguments.

Required Methods§

source

fn record_arg_with_span<A>( &mut self, source_map: &SourceMap, event_arg: A, span: Span )where A: Borrow<str> + Into<String>,

Records the following event arguments within the current generic activity being profiled:

  • the provided event_arg
  • a string representation of the provided span

Note: when self-profiling with costly event arguments, at least one argument needs to be recorded. A panic will be triggered if that doesn’t happen.
