Rust is adding raw identifiers in the 2018 edition:

https://rust-lang-nursery.github.io/edition-guide/2018/transitioning/raw-identifiers.html

The gdb lexer should implement this as well.

    Implement Rust raw identifiers
    
    This patch implements Rust raw identifiers in the lexer in gdb.  There
    was an earlier patch to do this, but the contributor didn't reply to
    my email asking whether he had sorted out his copyright assignment.
    
    This is relatively straightforward, but a small test suite addition
    was needd to ensure that the new test is skipped on older versions of
    rustc -- ones that predate the introduction of raw identifiers.
