It does not seem possible to use https://github.com/dtolnay/typetag to easily convert from TOML to boxed trait objects for WASM, but it works with native compilation.

The use of https://github.com/mmastrac/rust-ctor might be the reason, since it uses low level file format manipulation to start code execution. There is no such thing in WASM, or at least here is a start section, but even so, the technique would be different than the one currently used by ctor.

I seem to be correct on the issue:

mmastrac/rust-ctor#14
rustwasm/wasm-bindgen#1216
