Examples for my rust fork with wasm exception support

Simple examples for native wasm exceptions with rust

Important notes

Those examples are designed for the fork https://github.com/mirkootter/rust-wasm-exceptions

To try those examples, build a wasm32-wasi toolchain using this fork and run

cargo build --release

in the example's directory. The .cargo/config.toml already contains the necessary command line arguments and the target.

How to run the resulting wasm files?

NodeJS

You can use the runner.mjs script in this repository:

node runner.mjs hello_panic.wasm 

This should result in the following output:

`r#try` called with ptr 0x1234
Dropped
Caught something!
  data     : 0x1234
  exception: "Oops"
This program terminates correctly.

In the browser

You can run the resulting wasm binaries in https://webassembly.sh
