Represents an expression within an arithmetic subsitution.

Generic over the representation of a variable name.

Variants

Var(T)

The value of a variable, e.g. $var or var.

Literal(isize)

A numeric literal such as 42 or 0xdeadbeef.

Pow(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left ** right.

PostIncr(T)

Returns the current value of a variable, and then increments its value immediately after, e.g. var++

PostDecr(T)

Returns the current value of a variable, and then decrements its value immediately after, e.g. var--

PreIncr(T)

Increments the value of a variable and returns the new value, e.g. ++var.

PreDecr(T)

Decrements the value of a variable and returns the new value, e.g. --var.

UnaryPlus(Box<Arithmetic<T>>)

Ensures the sign of the underlying result is positive, e.g. +(1-2).

UnaryMinus(Box<Arithmetic<T>>)

Ensures the sign of the underlying result is negative, e.g. -(1+2).

LogicalNot(Box<Arithmetic<T>>)

Returns one if the underlying result is zero, or zero otherwise, e.g. !expr.

BitwiseNot(Box<Arithmetic<T>>)

Flips all bits from the underlying result, e.g. ~expr.

Mult(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left * right

Div(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left / right

Modulo(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left % right

Add(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left + right

Sub(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left - right

ShiftLeft(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left << right

ShiftRight(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left >> right

Less(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left < right

LessEq(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left <= right

Great(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left > right

GreatEq(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left >= right

Eq(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left == right

NotEq(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left != right

BitwiseAnd(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left & right

BitwiseXor(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left ^ right

BitwiseOr(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left | right

LogicalAnd(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left && right

LogicalOr(Box<Arithmetic<T>>, Box<Arithmetic<T>>)

left || right

Ternary(Box<Arithmetic<T>>, Box<Arithmetic<T>>, Box<Arithmetic<T>>)

first ? second : third

Assign(T, Box<Arithmetic<T>>)

Assigns the value of an underlying expression to a variable and returns the value, e.g. x = 5, or x += 2.

Sequence(Vec<Arithmetic<T>>)

expr[, expr[, ...]]
