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 will check that the input is fully parsed. If there are any unparsed tokens at the end of the stream, an error is returned.
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 is available only if Syn is built with the "parsing" feature.
