Enum rustc_parse::parser::FlatToken

pub enum FlatToken {
    Token(Token),
    AttrTarget(AttributesData),
    Empty,
}

A helper struct used when building an AttrTokenStream from a LazyAttrTokenStream. Both delimiter and non-delimited tokens are stored as FlatToken::Token. A vector of FlatTokens is then ‘parsed’ to build up an AttrTokenStream with nested AttrTokenTree::Delimited tokens.

Variants

Token(Token)

A token - this holds both delimiter (e.g. ‘{’ and ‘}’) and non-delimiter tokens

AttrTarget(AttributesData)

Holds the AttributesData for an AST node. The AttributesData is inserted directly into the constructed AttrTokenStream as an AttrTokenTree::Attributes.

Empty

A special ‘empty’ token that is ignored during the conversion to an AttrTokenStream. This is used to simplify the handling of replace ranges.

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.
