About

Booleans in Rust are represented by the bool type, which values can be either true or false.

Rust supports one boolean negation operator: ! (Not).

Rust supports six comparison operators: == (Equal), != (Not equal), > (Greater than), < (Less than), >= (Greater than or equal to), <= (Less than or equal to). They can be used to evaluate the relationship of non-boolean values into a boolean value.

1 > 0 // true
1 < 0 // false
1 == 0 // false
1 != 0 // true
1 >= 0 // true
1 <= 0 // false

Unlike some other languages, 0 is not false and non-zero is not true.

Rust supports three logical binary operators: & (Logical And), | (Logical Or), ^ (Logical Xor).

Rust supports two boolean operators: || (Or), && (And). They differ from | and & in that the right-hand operand is only evaluated when the left-hand operand does not already determine the result of the expression. That is, || only evaluates its right-hand operand when the left-hand operand evaluates to false, and && only when it evaluates to true.

true || false // == true; the right-hand side was not evaluated
true && false // == false
