cannot work on wasm32-unknown-unknown target from rust

[walksanatora]

when compiling for this target and then running wasm2lua on it you end up with

Unsupported export type: 0x2
/usr/lib/node_modules/wasm2lua/resources/patches/decoder.js:618
          throw new _helperApiError.CompileError("Unexpected valtype: " + toHex(valtypeByte));
          ^

same error when exporting from wasm32-wasi

[walksanatora]

nvm. but when exporting with wasm32-wasi it does complain at me Unsupported export type: 0x2

[walksanatora]

and after modifying the basic function to export the add function properly you then get met with

/usr/lib/node_modules/wasm2lua/resources/patches/decoder.js:1314
      if (sectionId !== _helperWasmBytecode.default.sections.custom) throw new _helperApiError.CompileError("Unexpected section: " + toHex(sectionId));

@walksanatora if you want a webassembly to luau solution probably https://github.com/Rerumu/Wasynth is your best bet. although just noticed you have an issue there too, unfortunately a bit late then.

wasm2lua is still nice for everything else since they actually did the hard part supporting native lua, without luajit's ffi.
