Introduce proc_macro::Span::source_text A function to extract the actual source behind a Span. Background: I would like to use `syn` in a `build.rs` script to parse the rust code, and extract part of the source code. However, `syn` only gives access to proc_macro2::Span, and i would like to get the source code behind that. I opened an issue on proc_macro2 bug tracker for this feature https://github.com/alexcrichton/proc-macro2/issues/110 and @alexcrichton said the feature should first go upstream in proc_macro. So there it is! Since most of the Span API is unstable anyway, this is guarded by the same `proc_macro_span` feature as everything else. |
