Why is this line hardcoded to a path?

https://github.com/projectfluent/fluent-rs/blob/f2033ce8340e09000ad9efccd6215b3fa5c23496/fluent-resmgr/src/resource_manager.rs#L174 It seems that if I try to change the path in my program to something like this: ``` . ├── broken │   └── resources │   ├── en-US │   │   └── test.ftl │   └── pl ├── Cargo.lock ├── Cargo.toml └── src └── main.rs ``` I get this: ``` thread 'main' panicked at /home/henry/.cargo/registry/src/index.crates.io-6f17d22bba15001f/fluent-resmgr-0.0.7/src/resource_manager.rs:175:56: called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" } note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` With this code: ```rs use fluent_fallback::Localization; use fluent_resmgr::ResourceManager; use unic_langid::langid; fn main() { let res_mgr = ResourceManager::new("./broken/resources/{locale}/".into()); let loc = Localization::with_env( vec!["test.ftl".into()], true, vec![langid!("en-US")], res_mgr, ); let bundles = loc.bundles(); let mut errors = vec![]; let value = bundles .format_value_sync("hello-world", None, &mut errors) .expect("Failed to format a value"); println!("{}", value.unwrap()); } ```
