Background: I'm using
rustc 1.53.0-nightly. I'm trying to create an AST using rustc. The first step is to create a parser. For this, I want to use new_parser_from_source_str. To create the parser, I also need to provide a ParseSess. Creating this ParseSess is where I'm having trouble.
Code: I'm executing the following:
let codemap = Rc::new(SourceMap::new(source_map::FilePathMapping::empty())); let handler = Handler::with_emitter(false, None, Box::new(emitter)); let parse_sess = ParseSess::with_span_handler(handler, codemap);
Error: Executing the above gives the following error:
thread 'main' panicked at 'cannot access a scoped thread local variable without calling `set` first', /mnt/c/Users/prgzz/.cargo/registry/src/github.com-1ecc6299db9ec823/scoped-tls-1.0.0/src/lib.rs:168:9
This problem is very similar to the one here. However, there doesn't seem to be a solution mentioned for it.
It would be great if someone could help me here, and, if not, direct me to the right place (if there is a more appropriate channel). I've been stuck with this for a few days now. I did come across a few related discussions, but none seems to address the problem properly.
