Struct Profiler 

pub struct Profiler { /* private fields */ }

Accumulates wall-clock measurements for repeated operations.

Typical use:

let mut p = Profiler::new("open");
p.start();
// ... do work ...
p.stop();
println!("{}", p.report());

Implementations

impl Profiler

pub fn new(name: impl Into<String>) -> Self

Create a new profiler with the given name.

pub fn start(&mut self)

Start a timing lap.

Calling start when a lap is already running resets the start time.

pub fn stop(&mut self)

Stop the current timing lap and record the measurement.

If start was never called, this is a no-op.

pub fn report(&self) -> String

Returns a human-readable statistics table.

Columns: count | min ms | mean ms | median ms | p95 ms | p99 ms | max ms

pub fn export_json(&self) -> Result<String>

Serialise the statistics + raw measurements to a pretty-printed JSON string.

Errors

Returns an error if JSON serialisation fails (should not happen in practice).
