Ivan Enderlin 4fe8286b81 feat(runtime-c-api) Avoid undefined behavior with user-given version. 
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.

Wasmer Libraries

Wasmer is modularized into different libraries, separated into three main sections:

Runtime

The core of Wasmer is the runtime, which provides the necessary abstractions to create a good user experience when embedding.

The runtime is divided into two main libraries:

  • runtime-core: The main implementation of the runtime.
  • runtime: Easy-to-use API on top of runtime-core.

Integrations

The integration builds on the Wasmer runtime and allow us to run WebAssembly files compiled for different environments.

Wasmer intends to support different integrations:

  • WASI: run WebAssembly files with the WASI ABI.
  • Emscripten: run Emscripten-generated WebAssembly files, such as Lua or nginx.
  • Go ABI: we will work on this soon! Want to give us a hand? ✋
  • Blazor: research period, see tracking issue

Backends

The Wasmer runtime is designed to support multiple compiler backends, allowing the user to tune the codegen properties (compile speed, performance, etc) to best fit their use case.

Currently, we support multiple backends for compiling WebAssembly to machine code:

  • singlepass-backend: Single pass backend - super fast compilation, slower runtime speed
  • clif-backend: Cranelift backend - slower compilation, normal runtime speed
  • llvm-backend: LLVM backend - slow compilation, native runtime speed
