# Struct syn::ExprUnary [−] [src]

    pub struct ExprUnary {
        pub attrs: Vec<Attribute>,
        pub op: UnOp,
        pub expr: Box<Expr>,
    }

A unary operation: `!x`, `*x`.

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

## Fields

`attrs: Vec<Attribute>` `op: UnOp` `expr: Box<Expr>`
