This library provides macros to get the difference of variables caused by a procedure.
Before and after the operation, use the pretty-print format by fmt::Debug to string them, and get their diff.
# Cargo.toml
[dependencies]
diff-ba-rs = "0.1.0"
use diff_ba_rs::prelude::*;
#[derive(Debug)]
struct ComplexVariable {
// ...
}
let mut complex_variable = ComplexVariable {
// ...
};
let _result = diff_ba::dbg!(&complex_variable, {
// OPERATION YOU WANT TO VERIFY
// The diff_ba::dbg! macro returns the final expression in this block.
});
use diff_ba_rs::prelude::*;
let mut a = 2;
let b = diff_ba::dbg!(&a,
a *= 2;
a + 1
});
// prints:
// ```
// - 2
// + 4
// ```
assert_eq!(b, 5);
For now, only the dbg! macro prints to standard output, but if there is demand for it from myself or others, I may implement a macro that returns a string or writes to a file.
