Struct MemoryTracker 

pub struct MemoryTracker { /* private fields */ }

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

Example

use fastapi_core::bench::MemoryTracker;

let mut tracker = MemoryTracker::new();

// ... do some work ...
tracker.sample();

// ... do more work ...
tracker.sample();

let report = tracker.report();
println!("{report}");

Implementations

impl MemoryTracker

pub fn new() -> Self

Create a new memory tracker, recording the current RSS as baseline.

pub fn sample(&mut self)

Take a memory sample at the current moment.

pub fn measure<F, R>(&mut self, f: F) -> R

where F: FnOnce() -> R,

Record a sample while executing a closure, returning the closure’s result.

pub fn measure_repeated<F>(&mut self, iterations: usize, f: F)

where F: FnMut(),

Record N iterations of a closure, sampling after each.

pub fn sample_count(&self) -> usize

Number of samples taken (excluding baseline).

pub fn baseline(&self) -> MemorySnapshot

Get the baseline memory snapshot.

pub fn peak_rss(&self) -> usize

Get the peak RSS observed.

pub fn report(&self) -> MemoryReport

Generate a memory usage report.

pub fn reset(&mut self)

Reset the tracker with a new baseline.

Trait Implementations

impl Default for MemoryTracker

fn default() -> Self

Returns the “default value” for a type.
