Enum ComparisonOperator 

pub enum ComparisonOperator {
    Equal,
    NotEqual,
    Less,
    Greater,
    LessOrEqual,
    GreaterOrEqual,
}

A comparison operator, yielding a boolean.

Measured behaviors worth knowing:

• Comparing two strings ignores case: "ABC" == "abc" is true.
• A string compared with a number is converted to a number first.
• Two non-zero real values compare to 14 significant digits.
• NAN and IND count as equal to each other.

Variants

Equal

Equality, ==.

NotEqual

Inequality, !=.

Less

Less than, <.

Greater

Greater than, >.

LessOrEqual

Less than or equal, <=.

GreaterOrEqual

Greater than or equal, >=.

Implementations

impl ComparisonOperator

pub const ALL: [Self; 6]

Every comparison operator.

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

How the operator is written.

pub const fn arity(self) -> Arity

Always two operands.

pub const fn precedence(self) -> u8

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