Expand description

Assert that two iterables produce equal sequences, with the same semantics as equal(a, b).

Panics on assertion failure with a message that shows the two iteration elements.

assert_equal("exceed".split('c'), "excess".split('c'));
// ^PANIC: panicked at 'Failed assertion Some("eed") == Some("ess") for iteration 1',
