Can't parse_macro_input with what used to be AttributeArgs

[glandium]

The release notes for syn 2 say that AttributeArgs was removed, and says to use Punctuated<Meta, Token![,]> instead. But while parse_macro_input!(foo as AttributeArgs) worked with syn 1, the equivalent (with Punctuated<Meta, Token![,]>) doesn't work with syn 2 because ParseMacroInput is gone, and Punctuated doesn't implement Parse. How does one do the equivalent of parse_macro_input!(foo as AttributeArgs) with syn 2?

You're looking for syn::meta::parser(), which includes an example able to parse:

#[tea(kind = "EarlGrey", hot, with(sugar, milk))]

Thanks, that was useful.
