The memmap crate doesn't make it straightforward to have part of the region be writeable and part readonly. Since this is a fairly boutique use case, and we don't need all that much code, just use the low-level APIs directly. Also, introduce a concept of "tunables" for adjusting the parameters of the runtime.
Wasmtime: a WebAssembly Runtime.
A standalone wasm-only runtime for WebAssembly, using Cranelift.
This is a work in progress that is not currently functional, but under active development.
Goals include:
- Be a general-purpose engine for running WebAssembly code outside of browsers, usable both standalone or as a library embedded in a larger application.
- Support a variety of host APIs with fast calling sequences.
- Prototype syscall APIs that can be proposed for use in the WebAssembly Reference Sysroot.
- Facilitate testing, experimentation, and development around the Cranelift and Lightbeam JITs.
- Develop a the native ABI used for compiling WebAssembly suitable for use in both JIT and AOT to native object files.
It's Wasmtime.
