rust-timeit

This package provides a simple way of timing small bits of Rust code. It essentially serves as a command-line wrapper for criterion, allowing for quickly running micro-benchmark tasks.

It takes its inspiration, and some of its form, from Python's timeit library.

Installation

To install the stable version, install Rust and run cargo install rust-timeit.

To install from source, run cargo install --path . from the main directory.

Example

Which way of creating a zero-length string is fastest?

rust-timeit --perf instructions --setup 'let empty = String::new()' 'String::new()' 'String::from("")' 'empty.clone()' '"".to_owned()'

(Hint: String::new() is fastest)
