Ever needed a counter to see how many times a line of code is passed? Here you go.

Examples

Run without arguments to get basic debug information:

pass!(); // Stderr: [<count>][<line_number>]

You can pass a literal to have it printed:

// Stderr: [<count>][<line_number>] Special message
pass!("Special message");
// Stderr: [<count>][<line_number>] a
pass!('a');
// Stderr: [<count>][<line_number>] 5999999
pass(5999999)

You can pass a variable with the Display trait too:

let hw = String::from("Hello world");
let num = 5;
// Stderr: [<count>][<line_number>] Hello world
pass!(hw);
// Stderr: [<count>][<line_number>] 5
pass!(num);

lib.rs:

A simple counter for debugging.

Basic usage of the crate is calling pass, with each call incrementing a static counter. The counter starts at 0, and has a max of usize::MAX.
