Description
The below code worked until I updated today. I'm not sure which version of the nightly build I had previously, but it was about ten days old.
#![feature(rustc_private)]
extern crate syntax;
use syntax::parse;
use syntax::ast::{TokenTree};
use syntax::parse::{ParseSess};
fn parse_token_trees(source: &str) -> Vec<TokenTree> {
let session = ParseSess::new();
let source = source.into();
let mut parser = parse::new_parser_from_source_str(&session, vec![], "".into(), source);
parser.parse_all_token_trees().unwrap()
}
Rust Playpen (this produces the same error I am seeing)
If I change it to this, it compiles:
#![feature(rustc_private)]
extern crate syntax;
use syntax::parse;
use syntax::ast::{TokenTree};
use syntax::parse::{ParseSess};
fn parse_token_trees(source: &str) -> Vec<TokenTree> {
let session = ParseSess::new();
let source = source.into();
let mut parser = parse::new_parser_from_source_str(&session, vec![], "".into(), source);
let tts = parser.parse_all_token_trees().unwrap();
tts
}
