The Wasmer runtime crates

The crates can be grouped as follows.

• api — The public Rust API exposes everything a user needs to use Wasmer programatically through the wasmer crate,
• c-api — The public C API exposes everything a C user needs to use Wasmer programatically,
• cache — The traits and types to cache compiled WebAssembly modules,
• cli — The Wasmer CLI itself,
• compiler — The base for the compiler implementations, it defines the framework for the compilers and provides everything they need:
  • compiler-cranelift — A WebAssembly compiler based on the Cranelift compiler infrastructure,
  • compiler-llvm — A WebAssembly compiler based on the LLVM compiler infrastructure; recommended for runtime speed performance,
  • compiler-singlepass — A WebAssembly compiler based on our own compilation infrastructure; recommended for compilation-time speed performance.
• deprecated — The deprecated and old public Rust API, must not be used except if you don't want to migrate an old code using the 0.x version of Wasmer to 1.x,
• derive — A set of procedural macros used inside Wasmer,
• ABI:
  • emscripten — Emscripten ABI implementation inside Wasmer,
  • wasi — WASI ABI implementation inside Wasmer.
• engine — The general abstraction for creating an engine, which is responsible of leading the compiling and running flow:
  • engine-universal —
  • engine-dylib —
  • engine-staticlib —
• middlewares —
• types —
• vm —
