Enum rustc_parse::parser::FlatToken

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

A helper struct used when building a AttrAnnotatedTokenStream from a LazyTokenStream. Both delimiter and non-delimited tokens are stored as FlatToken::Token. A vector of FlatTokens is then ‘parsed’ to build up a AttrAnnotatedTokenStream with nested AttrAnnotatedTokenTree::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 AttrAnnotatedTokenStream as a AttrAnnotatedTokenTree::Attributes

Empty

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