1310: upgrade the blake3 dependency to 0.2 r=MarkMcCaskey a=oconnor663 Version 0.2 makes assembly implementations available. They're off by default, and I haven't enabled them here, because they require the build machine to have a C toolchain installed. But if that's already a requirement for Wasmer, we could enable them with the `"c"` feature, for both better runtime performance and faster build times.

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.
- Your own ABI: Do you want to create your own ABI? Here's a repo showcasing how!
- 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
