Enum AttrItemKind 

pub enum AttrItemKind {
    Parsed(EarlyParsedAttribute),
    Unparsed(AttrArgs),
}

Some attributes are stored in a parsed form, for performance reasons. Their arguments don’t have to be reparsed everytime they’re used

Variants

Parsed(EarlyParsedAttribute)

Unparsed(AttrArgs)

Layout

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.
