Expand description

Assert a value is less than or equal to an expression.

  • If true, return ().

  • Otherwise, call panic! with a message and the values of the expressions with their debug representations.

§Examples

let a = 1;
let b = 2;
assert_le!(a, b);

let a = 2;
let b = 1;
assert_le!(a, b);
// assertion failed: `assert_le!(a, b)`
//  a label: `a`,
//  a debug: `2`,
//  b label: `b`,
//  b debug: `1`,
//        a: `2`,
//        b: `1`
