Struct syn::ExprUnary

source · [−]

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

Expand description

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: UnOpexpr: Box<Expr>
