Enum syn::UnOp

source · [−]

pub enum UnOp {
    Deref(Star),
    Not(Bang),
    Neg(Sub),
}

Available on crate features full or derive only.

Expand description

A unary operator: *, !, -.

This type is available only if Syn is built with the "derive" or "full" feature.

Variants

The * operator for dereferencing

`Not(Bang)`

The ! operator for logical inversion

`Neg(Sub)`

The - operator for negation
