Struct MetricsObserver 

pub struct MetricsObserver {
    pub resolution_count: AtomicU64,
    pub total_resolution_time: AtomicU64,
    pub panic_count: AtomicU64,
}

Performance-focused observer that tracks detailed metrics.

Collects timing data, resolution counts, and failure rates for post-workflow analysis and optimization.

Fields

resolution_count: AtomicU64

total_resolution_time: AtomicU64

panic_count: AtomicU64

Implementations

impl MetricsObserver

pub fn new() -> Self

Creates a new metrics observer.

pub fn resolution_count(&self) -> u64

Gets the total number of resolutions observed.

pub fn average_resolution_time(&self) -> Option<Duration>

Gets the average resolution time in nanoseconds.

pub fn total_resolution_time(&self) -> Duration

Gets the total resolution time.

pub fn panic_count(&self) -> u64

Gets the number of panics observed.

pub fn reset(&self)

Resets all metrics.
