Enum syn::UnOp

#[non_exhaustive]
pub enum UnOp {
    Deref(Star),
    Not(Not),
    Neg(Minus),
}

A unary operator: *, !, -.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Deref(Star)

The * operator for dereferencing

Not(Not)

The ! operator for logical inversion

Neg(Minus)

The - operator for negation
