Compilation error in wirefilter-parser

[bluebear94]

I’m trying to run the tests for this crate, but it doesn’t compile on a current Rust version.

$ cargo test --workspace
(other output...)

I know literally nothing about rust but am interested in this project. I also ran into the same errors. The errors went away after I did cargo update which updated dependency versions I think. After that, just saw test failures which are easy to fix.

rustup 1.26.0 (2023-04-05)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.70.0 (90c541806 2023-05-31)`

The wirefilter library in the engine crate no longer uses the pest based parser in the wirefilter-parser crate, there is a handwritten parser in the wirefilter crate which is a lot better, more performant and with better errors for the wirefilter syntax.

@cch0 what did you do to fix the tests?

@cch0 I spoke too soon I understand now.
