// This is using the `tokio` runtime. You'll need the following dependency:
//
// `tokio = { version = "0.2", features = ["macros"] }`
async
// The [cfg(not(target_arch = "wasm32"))] above prevent building the tokio::main function
// for wasm32 target, because tokio isn't compatible with wasm32.
// If you aren't building for wasm32, you don't need that line.
// The two lines below avoid the "'main' function not found" error when building for wasm32 target.
