Enum LogicalOperator 

pub enum LogicalOperator {
    And,
    Or,
    Not,
}

A logical operator, working on truth values.

These are the symbol forms only. The word forms AND, OR, XOR and NOT are bitwise, see BitwiseOperator, which is the single most common misreading of the expression language.

Variants

And

Logical and, &&.

Or

Logical or, ||.

Not

Logical not, !.

Implementations

impl LogicalOperator

pub const ALL: [Self; 3]

Every logical operator.

pub const fn symbol(self) -> &'static str

How the operator is written.

pub const fn arity(self) -> Arity

How many operands it takes.

pub const fn precedence(self) -> u8

Binding strength; lower binds tighter. Measured, see super.
