Ever need to 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:

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

You can pass a literal to have it printed:

rust // 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:

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