An experimental GUI framework for Rust, backed by per-platform native widgets. React, AppKit/UIKit inspired. EXPERIMENTAL, runs on Cocoa right now. ;P

alchemy's Issues

Example at https://alchemy.rs/ does not compile

I tried to copy the example provided at https://alchemy.rs/ at it is without any modification and got this error message:

Some errors occurred: E0412, E0433.
For more information about an error, try `rustc --explain E0412`.
error: Could not compile `alchemy`.

To learn more, run the command again with --verbose.

From the error message looks to be something to do with Alchemy. I'm on Ubuntu 19.04 x64 using Rust 1.34.

Unable to compile example - cannot infer type, consider giving `result` a type
