❗️⚠️ Contains #1028, must be merged before this one.

This patch introduces 2 new functions:

  • wasmer_wasi_generate_import_object_for_version and
  • wasmer_wasi_get_version.

It mimics the current API provided by wasmer_wasi, nothing fancy
here. It's just a regular port to C/C++.

Because wasmer_wasi::get_wasi_version returns an option, and in
order to simplify the C/C++ API, wasmer_wasi_get_version can return
Version::Unknown in case of an error. It's up to the user to check
the version is valid (i.e. not unknown).

To see only the changes provided by this PR (excluding #1028), check Hywan/wasmer@fix-wasi-get-version...feat-runtime-c-api-wasi-version.

Looks reasonable, though see my feedback on #1028 ; I think we should probably add a new method if we want to do fuzzy matching on module's import signatures

… WASI version.

This patch introduces 2 new functions:

* `wasmer_wasi_generate_import_object_for_version` and
* `wasmer_wasi_get_version`.

It mimics the current API provided by `wasmer_wasi`, nothing fancy
here. It's just a regular port to C/C++.

Because `wasmer_wasi::get_wasi_version` returns an option, and in
order to simplify the C/C++ API, `wasmer_wasi_get_version` can return
`Version::Unknown` in case of an error. It's up to the user to check
the version is valid (i.e. not unknown).
This patch updates `test-wasi-import-object` to test the new
`wasmer_wasi_get_version` &
`wasmer_wasi_generate_import_object_for_version` functions, and the
new `Version` type.
When the version has type `Version`, we expect the user to give a
valid `Version` variant. Since the `Version` is basically a `uint8_t`,
the user is able to pass everything she wants, which can create an
undefined behavior on the Rust side.

To avoid such situation, the version has now type `c_uchar` (`unsigned
char` or `uint8_t` on C side —on most platforms). Then the `From`
trait is implemented on `Version`. In case the value is unbound,
`Version::Unknown` is returned.
0 matches to `Unknown`, 1 matches to `Snapshot0` and 2 matches to
`Snapshot1`.

92: feat(wasi) Support `WasiGetVersion` & other `*ForVersion` WASI API r=Hywan a=Hywan

Fix #90.
Fix #77.

⚠️ Depends on wasmerio/wasmer#1028, wasmerio/wasmer#1029, and wasmerio/wasmer#1030. They must be merged before merging this PR! Marking this PR as a draft to be sure (the shared libraries must be updated too).

This patch updates `bridge.go` and `wasmer.h` to support the new `wasmer_wasi_generate_import_object_for_version` and `wasmer_wasi_get_version` functions.

After that, this patch updates `wasi.go` to implement the new `NewDefaultWasiImportObjectForVersion`, `NewWasiImportObjectForVersion` and the `WasiGetVersion` functions. In addition to that, we create a new `WasiVersion` type.

Finally, this patch updates the tests to test this new API. And it works like a charm 👌.
