Can you run this app now?

Hello, I'm a newer for rust. I tried to run this app following by the guide, but got some error below.

Can you please help me run this app? Thanks.

Hi @nanqic, this project is outdated, I would suggest to look at:

• Seed examples: https://github.com/seed-rs/seed/tree/master/examples
• Trunk example with Seed: https://github.com/thedodd/trunk/tree/master/examples/seed
• Or perhaps MoonZoon could be a bit easier to start with because it has own CLI tools and then you can return to Seed

[nanqic]

Okey, thank you for your suggest!

Hey @nanqic - I ran into this as well, and it can be resolved by changing Closure::new( .. ) in routing.rs line 113 to <Closure<_> as ClosureNew<_>>::new( .. ).

Seems related to seed-rs/seed#698, though I'm not sure why that's an issue here.
