Module assert_fn

Assert for comparing functions.

These macros help compare functions that return anything. The macros call the functions, then compare the return values.

Compare a function with another function:

• assert_fn_eq!(function1, function2) ≈ function1() = function2()

• assert_fn_ne!(function1, function2) ≈ function1() ≠ function2()

• assert_fn_ge!(function1, function2) ≈ function1() ≥ function2()

• assert_fn_gt!(function1, function2) ≈ function1() > function2()

• assert_fn_le!(function1, function2) ≈ function1() ≤ function2()

• assert_fn_lt!(function1, function2) ≈ function1() < function2()

Compare a function with an expression:

• assert_fn_eq_expr!(function, expr) ≈ function() = expr

• assert_fn_ne_expr!(function, expr) ≈ function() ≠ expr

• assert_fn_ge_expr!(function, expr) ≈ function() ≥ expr

• assert_fn_gt_expr!(function, expr) ≈ function() > expr

• assert_fn_le_expr!(function, expr) ≈ function() ≤ expr

• assert_fn_lt_expr!(function, expr) ≈ function() < expr

Example

use assertables::*;

let a: i8 = -1;
let b: i8 = 1;
assert_fn_eq!(i8::abs, a, i8::abs, b);
