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.
