Enum rustc_ast::ast::UnOp

source · [−]

pub enum UnOp {
    Deref,
    Not,
    Neg,
}

Expand description

Unary operator.

Note that &data is not an operator, it’s an AddrOf expression.

Variants

`Deref`

The * operator for dereferencing

`Not`

The ! operator for logical inversion

`Neg`

The - operator for negation
