Unable to compile with the dialog feature enabled

[Isaac-Leonard]

When adding the dialog feature to my project I get compilation errors.

error: could not compile `tauri-sys` (lib) due to 2 previous errors

My cargo.toml has this for kauri-sys:

tauri-sys = { git = "https://github.com/JonasKruckenberg/tauri-sys", rev = "904450c", features = [
"dialog"
] }

I'm happy to make a pull request later today if this is just a name conflict issue as the error seems to suggest

[Isaac-Leonard]

Okay, I can get it to compile fine when cloning this repo so not sure what's going on

[Isaac-Leonard]

It seems like it depends on the rust version I'm using with issues happening in the currently nightly iteration

[Isaac-Leonard]

Adding the following to rust-toolchain.toml in my project seems to fix it for now:

[toolchain]
channel = "nightly-2023-06-15"

With the error I encountered while attempting to compile the current tauri-sys repo with the current nightly edition being:

error[E0635]: unknown feature `proc_macro_span_shrink`
  --> /Users/isaac/.cargo/registry/src/index.crates.io-6f17d22bba15001f/proc-mac

92 |     feature(proc_macro_span, proc_macro_span_shrink)
   |                              ^^^^^^^^^^^^^^^^^^^^^^

For more information about this error, try `rustc --explain E0635`.
error: could not compile `proc-macro2` (lib) due to previous error
warning: build failed, waiting for other jobs to finish...

Not sure if this was the cause of the original errors but I'll mark this as closed for now as I seem to have a solution and the issue doesn't appear to be in the kauri-sys code.
