Struct Benchmark

pub struct Benchmark { /* private fields */ }

Holds the times for read, write and blend operations.

Implementations

impl Benchmark

pub fn new() -> Self

Creates a new instance of the Benchmark struct with counters set to zero.

pub fn total(&self) -> f64

Returns the total time (in milliseconds), i.e., the sum of read, write and blend times.

pub fn execute<F, T, H>(&mut self, update_fn: H, target_fn: F) -> T

where F: FnOnce() -> T, H: FnOnce(&mut Self, f64),

Executes the function to benchmark and adds the time spent to a certain counter with the given target_fn.

use pconvert_rust::benchmark::Benchmark;
use pconvert_rust::utils::read_png_from_file;

let mut benchmark = Benchmark::new();
let demultiply = false;
let path = "path/to/file.png".to_owned();
let top = benchmark.execute(Benchmark::add_read_png_time, || {
   read_png_from_file(path, demultiply)
}).unwrap();

pub fn add_blend_time(benchmark: &mut Benchmark, blend_time: f64)

Adds time spent blending to the blend time counter.

pub fn add_read_png_time(benchmark: &mut Benchmark, read_png_time: f64)

Adds time spent reading to the read time counter.

pub fn add_write_png_time(benchmark: &mut Benchmark, write_png_time: f64)

Adds time spent writing to the write time counter.
