Module bench 

Latency measurement and benchmarking utilities.

Provides tools for measuring request processing latency with percentile tracking, histogram distribution, and reporting.

Example

use fastapi_core::bench::{LatencyHistogram, BenchmarkRunner, BenchmarkConfig};

let config = BenchmarkConfig::new("simple_get")
    .warmup_iterations(100)
    .iterations(10_000);

let report = BenchmarkRunner::run(&config, || {
    // exercise some code path
});

println!("{report}");

Structs

HistogramBucket

A single histogram bucket.

LatencyComparison

Comparison between current and baseline latency reports.

LatencyHistogram

Collects latency samples and computes percentile statistics.

LatencyReport

Summary report of latency measurements.

MemoryComparison

Comparison between two memory reports.

MemoryReport

Report summarizing memory usage measurements.

MemorySnapshot

A snapshot of memory usage at a point in time.

MemoryTracker

Tracks memory usage over time with baseline, peak, and delta computation.

Functions

format_bytes_size

Format a byte count in human-readable form.

format_duration
