Struct HealthMonitor 

pub struct HealthMonitor { /* private fields */ }

A wrapper that monitors parser health and provides graceful degradation

This wraps any parser function to track how many events are being ignored and emit warnings when the parser seems to be misconfigured.

Implementations

impl HealthMonitor

pub fn new(parser_name: &'static str) -> Self

Create a new health monitor for a parser

pub fn record_parsed(&self)

Record that an event was parsed successfully

pub fn record_ignored(&self)

Record that an event was ignored

pub fn record_unknown_event(&self)

Record an unknown event type (valid JSON but unhandled)

pub fn record_parse_error(&self)

Record a parse error (malformed JSON)

pub fn record_control_event(&self)

Record a control event (state management with no user-facing output)

pub fn record_partial_event(&self)

Record a partial/delta event (streaming content displayed incrementally)

Partial events represent streaming content that is shown to the user in real-time as deltas. These are NOT errors and should not trigger health warnings.

pub fn check_and_warn(&self, colors: Colors) -> Option<String>

Check if we should warn about parser health (only warn once)
