Variants§

§

Error

§

Log(Box<Expr>)

Outputs the value of the contained Expr as a log.

§

Block(Vec<Box<Stmt>>, Option<Box<Expr>>)

§

If(Box<Expr>, Box<Expr>, Option<Box<Expr>>)

The first Expr is the condition, the second the “true” block, and the third the “false” block.

Else-if statements are collapsed as if a standard if statement was put inside of the else block.

§

While(Box<Expr>, Vec<Box<Stmt>>)

While Expr is true, do Stmts.

§

Assign(Box<Expr>, AssignOp, Box<Expr>)

§

Binary(Box<Expr>, BinaryOp, Box<Expr>)

§

Unary(UnaryOp, Box<Expr>)

§

Property(Box<Expr>, String)

§

Index(Box<Expr>, Box<Expr>)

§

Call(Box<Expr>, Vec<Box<Expr>>)

§

Constant(Constant)
