Function counter

pub fn counter(
    context: &TraceCategoryContext,
    name: &'static CStr,
    counter_id: u64,
    args: &[Arg<'_>],
)

Writes a counter event with the specified id.

The arguments to this event are numeric samples and are typically represented by the visualizer as a stacked area chart. The id serves to distinguish multiple instances of counters which share the same category and name within the same process.

1 to 15 numeric arguments can be associated with an event, each of which is interpreted as a distinct time series.
