macro_rules! assert_approx_eq_as_result {
($a:expr, $b:expr $(,)?) => { ... };
}Expand description
Assert a number is approximately equal to another.
Pseudocode:
| a - b | ≤ 1e-6
-
If true, return Result
Ok(abs_diff, approx). -
When false, return
Errwith a message and the values of the expressions with their debug representations.
This macro provides the same statements as assert_, except this macro
returns a Result, rather than doing a panic.
This macro is useful for runtime checks, such as checking parameters, or sanitizing inputs, or handling different results in different ways.
