Enum FlatToken

Source

enum FlatToken {
    Token((Token, Spacing)),
    AttrsTarget(AttrsTarget),
    Empty,
}

Expand description

A helper struct used when building a TokenStream 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 TokenStream with nested TokenTree::Delimited tokens.

Variants§

§

Token((Token, Spacing))

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

§

AttrsTarget(AttrsTarget)

Holds the AttrsTarget for an AST node. The AttrsTarget is expanded directly into the constructed TokenStream.

§

Empty

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