Struct Attribute 

pub struct Attribute {
    pub name: Ident,
    pub arg: Option<AttrArg>,
    pub span: Span,
}

An attribute, #[name] or #[name(literal)] (M5a spec 2.2), written before an item, a struct field, an enum variant, a field of a variant, or a method. The parser keeps every one it reads; which names exist and where each may go is the compiler’s resolver’s to check.

Fields

name: Ident

arg: Option<AttrArg>

What is between the parentheses; None when there are none.

span: Span

From # through ].
