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
ic!()src/example.rs
```rust
extern crate icecream;
mod amodule { fn somefunction() { 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) ```
