Compilation fails using rust 1.0.0-beta

Attempting to compile the plugin using "mvn package" on Mac OS X 10.10.3, using Java 8 and the newest Rust 1.0.0-beta, results in the following errors:

Thanks for the report

If I understand this plugin now depends on native parsing and some unstable features (syntax::ast). With beta/release version of Rust there isn't possible to use unstable features anymore. Is there any plan how to fix this problem? For example move back to the java parsing (antlr) or wait for stabilization of syntax::ast library?

[drrb]

That's correct: I put the plugin on hold for a while after Rust disabled unstable features in its stable releases. I'm in the process of moving back to a Java parser (writing a new one, which will hopefully be faster than the old ANTLR one). The more advanced compilation features (error reporting, etc) will hopefully be provided by the Rust Language Server.
