Example for 'exports-memory' does not seem to work?

[kmott]

Summary

Hello, I am working through the examples, and I noticed exports-memory does not seem to work if I create it as a standalone project.

  |
1 | use wasmer::{imports, wat2wasm, Instance, Module, Store, TypedFunction, WasmPtr};
  |                                                          ^^^^^^^^^^^^^ no `TypedFunction` in the root

If I check out the main wasmer repo and run the example with cargo run --example exported-memory --release --features "cranelift" it works just fine.

I wonder if when the NativeFunc -> TypedFunction rename occurred, the examples got updated as well, but the 2.3.0 version of wasmer does not support the new TypedFunction yet (I think this may occur with a few other examples as well)?

I wonder if when the NativeFunc -> TypedFunction #2939 occurred, the examples got updated as well, but the 2.3.0 version of wasmer does not support the new TypedFunction yet (I think this may occur with a few other examples as well)?

Looking at the list of changed files, I'd say breaking changes happened in nearly all the examples.

But is this a problem? Couldn't you just grab the example for wasmer 2.3.0?

Thanks for repoting the issue. The current examples have changed from the 2.3.0 API so that's why you are encountering the issue.

If you use the file from the 2.3.0 tag things should work properly. Sorry for the confussion, as soon as we release the Wasmer 3.0 beta it should be solved.
