icecream-rs

Print debugging with inspection for Rust, inspired by icecream for Python.

I tend to use a lot of print debugging when writing Rust. icecream provides the ic!() macro to make print debugging more convenient by formatting print statements with helpful information like:

• line number
• calling function
• module name
• file name

Debugging with ic!()

src/example.rs

#[macro_use]
extern crate icecream;

mod a_module {
    fn some_function() {
        let x = Some(99);
        ic!();
    }
}

ic!() with no parameters prints the line number and calling function:

7 | some_function

ic!(f) (full) prints more information:

7 | a_module::some_function

ic!(ff) (full) prints even more information:

7 | example.rs::a_module::some_function

ic!(x) with a variable prints the name of the variable and the value formatted with std::fmt::Debug.

7 | some_function
> x = Some(99)
