pub fn parse2<T: Parse>(tokens: TokenStream) -> Result<T>Expand description
Parse a proc-macro2 token stream into the chosen syntax tree node.
This function parses a proc_macro2::TokenStream which is commonly useful
when the input comes from a node of the Syn syntax tree, for example the
body tokens of a Macro node. When in a procedural macro parsing the
proc_macro::TokenStream provided by the compiler, use syn::parse
instead.
This function enforces that the input is fully parsed. If there are any unparsed tokens at the end of the stream, an error is returned.
