Operators Reference

Arithmetic

Operator	Description	Example
+	Addition	a + b
-	Subtraction / negation	a - b, -x
*	Multiplication	a * b
/	Division	a / b
%	Modulo	a % b

Comparison

All comparisons compile to strict equality (===, !==).

Operator	Description	Compiles to
==	Equal	===
!=	Not equal	!==
<	Less than	<
>	Greater than	>
<=	Less or equal	<=
>=	Greater or equal	>=

Logical

Operator	Description	Example
&&	Logical AND	a && b
||	Logical OR	a || b
!	Logical NOT	!a

Pipe

Operator	Description	Example
|>	Pipe	x |> f

The pipe operator passes the left side as the first argument to the right side. Use _ as a placeholder for non-first-argument positions.

x |> f          // f(x)
x |> f(a, _)    // f(a, x)
x |> f |> g     // g(f(x))
x |> match { ... }  // match x { ... }

Unwrap

Operator	Description	Example
?	Unwrap Result/Option	expr?

The ? operator unwraps Ok(value) or Some(value), and returns early with Err(e) or None on failure. Only valid inside functions that return Result or Option.

Arrow and Closure Operators

Operator	Context	Meaning
fn(x)	Closures	fn(x) x + 1
.field	Dot shorthand	.name (implicit field-access closure)
->	Match arms, return types, function types	Ok(x) -> x, fn(string) -> number
|>	Pipes	data |> transform
