Summary

bool is a type with two possible values: true and false

true and false are both literals

You can use the assert! macro to make sure expressions evaluate to true

You can use the six comparison operators to compare values and get bool results

Functions can return bools, just like they can return i32s and other types

The ! is the not operator, and it changes true to false and false to true

The six comparison operators form three pairs of operators that are the opposite of each other

&& is the and operator, and || is the or operator
