Struct rustc_ast::tokenstream::AttrsTarget

pub struct AttrsTarget {
    pub attrs: AttrVec,
    pub tokens: LazyAttrTokenStream,
}

Stores the tokens for an attribute target, along with its attributes.

This is constructed during parsing when we need to capture tokens, for cfg and cfg_attr attributes.

For example, #[cfg(FALSE)] struct Foo {} would have an attrs field containing the #[cfg(FALSE)] attr, and a tokens field storing the (unparsed) tokens struct Foo {}

The cfg/cfg_attr processing occurs in StripUnconfigured::configure_tokens.

Fields

attrs: AttrVec

Attributes, both outer and inner. These are stored in the original order that they were parsed in.

tokens: LazyAttrTokenStream

The underlying tokens for the attribute target that attrs are applied to

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.
