Enum GeneratedAttr 

pub enum GeneratedAttr {
    AutomaticallyDerived,
    RustcConstUnstableDerived,
    Inline,
    DocHidden,
    CoverageOff,
    RustcTestMarker(Symbol),
}

An attribute created by a macro expansion.

This attribute has no tokens, which means it cannot be allowed to re-enter the parser. This means it can only be added to items that cannot later be observed by other macros.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
