Operators

Arithmetic Operators

• +: Addition — returns the sum of two operands.
• -: Subtraction — returns the difference between two operands.
• *: Multiplication — returns the product of two operands.
• /: Division — returns the quotient of two operands.
• %: Modulo (remainder) — returns the remainder after division.

Comparison Operators

• ==: Equality — checks if two values are equal.
• !=: Inequality — checks if two values are not equal.
• <: Less than — checks if the left operand is smaller.
• >: Greater than — checks if the left operand is larger.
• <=: Less than or equal to — checks if the left operand is smaller or equal.
• >=: Greater than or equal to — checks if the left operand is larger or equal.

Logical Operators

• &&: Logical AND — returns true only if both operands are true.
• ||: Logical OR — returns true if at least one operand is true.
• !: Logical NOT — inverts the boolean value of its operand.

Bitwise Operators

• &: Bitwise AND — performs a bitwise AND on each bit.
• |: Bitwise OR — performs a bitwise OR on each bit.
• ^: Bitwise XOR — performs a bitwise exclusive OR on each bit.
• !: Bitwise NOT — inverts all bits in the operand.
• <<: Left shift — shifts bits to the left by the specified amount.
• >>: Right shift — shifts bits to the right by the specified amount.

Compound Assignment Operators

• +=: Addition assignment — adds the right operand to the left and assigns the result.
• -=: Subtraction assignment — subtracts the right operand from the left and assigns the result.
• *=: Multiplication assignment — multiplies the left operand by the right and assigns the result.
• /=: Division assignment — divides the left operand by the right and assigns the result.
• %=: Modulo assignment — computes the remainder and assigns the result.
• &=: Bitwise AND assignment — performs bitwise AND and assigns the result.
• |=: Bitwise OR assignment — performs bitwise OR and assigns the result.
• ^=: Bitwise XOR assignment — performs bitwise XOR and assigns the result.
• <<=: Left shift assignment — shifts left and assigns the result.
• >>=: Right shift assignment — shifts right and assigns the result.

Other Key Operators and Symbols

• .: Field access or method call — accesses a field or calls a method on an object.
• ..: Right-exclusive range literal — creates a range from start to end (exclusive).
• ..=: Right-inclusive range literal — creates a range from start to end (inclusive).
• ..: Struct literal update syntax — updates a struct with new values.
• ..: “And the rest” pattern binding — matches remaining fields in a pattern.
• ?: Error propagation — unwraps a Result or Option, propagating errors.
• &: Borrowing — creates a shared reference (&T) or mutable reference (&mut T).
• *: Dereference — accesses the value pointed to by a pointer.
• as: Type casting — converts a value from one type to another.
• :: Type annotation — specifies the type of a variable or expression.
• ;: Statement terminator — ends a statement or item.
• ->: Function return type — specifies the return type of a function or closure.
• @: Pattern binding — binds a name to a matched value in a pattern.
