Enum EarlyParsedAttribute 

pub enum EarlyParsedAttribute {
    CfgTrace(CfgEntry),
    CfgAttrTrace,
}

Some attributes are stored in parsed form in the AST. This is done for performance reasons, so the attributes don’t need to be reparsed on every use.

Currently all early parsed attributes are excluded from pretty printing at rustc_ast_pretty::pprust::state::print_attribute_inline. When adding new early parsed attributes, consider whether they should be pretty printed.

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.
