Struct CompilationMetrics 

Source 
pub struct CompilationMetrics { /* private fields */ }
Expand description

Global metrics for the JIT compilation pipeline.

All counters are atomic and use Relaxed ordering for minimal overhead (< 5ns per increment). Intended for dashboards and diagnostics, not for correctness-critical decisions.

Implementations§

Source§

impl CompilationMetrics

Source

pub fn new() -> Self

Creates a new metrics instance with all counters at zero.

Source

pub fn record_compiled(&self, compile_time_ns: u64)

Records a successful JIT compilation.

Source

pub fn record_fallback(&self)

Records a fallback to interpreted execution (plan not compilable).

Source

pub fn record_error(&self)

Records a compilation error.

Source

pub fn compiled_count(&self) -> u64

Returns the number of successfully compiled queries.

Source

pub fn fallback_count(&self) -> u64

Returns the number of fallback queries.

Source

pub fn error_count(&self) -> u64

Returns the number of errored queries.

Source

pub fn compile_time_total_ns(&self) -> u64

Returns total compilation time in nanoseconds.

Source

pub fn total_queries(&self) -> u64

Returns total number of queries (compiled + fallback + error).

Source

pub fn snapshot(&self) -> MetricsSnapshot

Takes a snapshot of all metrics.
