Trait PostProcessor 

pub trait PostProcessor: Send + Sync {
    // Provided methods
    fn process_log(&self, _event: &mut LogEvent) { ... }
    fn process_metric(&self, _event: &mut Metric) { ... }
    fn process_trace(&self, _event: &mut TraceEvent) { ... }
    fn process(&self, event: &mut EventMutRef<'_>) { ... }
}

A post-processing step applied to every event that flows through a SourceSender.

Implement this trait to mutate events just before they are placed on the output channel. Because each method receives a typed reference, it is impossible at the type level to accidentally change an event’s variant.

It is applied globally — to all outputs (default and named ports) produced by the same Builder.

Provided Methods

fn process_log(&self, _event: &mut LogEvent)

Called once for every crate::event::LogEvent in a batch.

fn process_metric(&self, _event: &mut Metric)

Called once for every crate::event::Metric in a batch.

fn process_trace(&self, _event: &mut TraceEvent)

Called once for every crate::event::TraceEvent in a batch.

fn process(&self, event: &mut EventMutRef<'_>)

Dispatches a single event to the appropriate typed method.

Override process_log, process_metric, or process_trace rather than this method unless you need to handle all variants uniformly.
