Struct CustomMetricsHandle 

pub struct CustomMetricsHandle { /* private fields */ }

Cheap, cloneable handle for custom metrics from the Lua bridge.

Wraps Arc<Mutex<CustomMetrics>> to match the Handle pattern used by BudgetHandle and ProgressHandle.

Poison policy

Silently skips on poison. Custom metrics are observational — a missed record degrades stats but does not affect execution.

Implementations

impl CustomMetricsHandle

pub fn record(&self, key: String, value: Value)

Record a key-value pair. Silently skips on mutex poison.

pub fn get(&self, key: &str) -> Option<Value>

Get a value by key. Returns None on mutex poison or missing key.

Trait Implementations

impl Clone for CustomMetricsHandle

fn clone(&self) -> CustomMetricsHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
