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