Expand description

Assert a infix operator, such as assert_infix!(a == b).

Pseudocode:
a infix b

  • If true, return ().

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

§Examples

use assertables::*;

let a = 1;
let b = 1;
assert_infix!(a == b);

// This will panic
let a = 1;
let b = 2;
assert_infix!(a == b);
// assertion failed: `assert_infix!(a == b)`
// https://docs.rs/assertables/…/assertables/macro.assert_infix.html
//  a label: `a`,
//  a debug: `1`,
//  b label: `b`,
//  b debug: `2`

§Infix operators

For values:

  • == equal
  • != not equal
  • < less than
  • <= less than or equal to
  • > greater than
  • >= greater than or equal to

For booleans:

  • ^ logical XOR
  • ! logical NOT
  • & logical AND
  • | logical OR
  • && logical lazy AND
  • || logical lazy OR
