* Refactor binary-compatible-builds for releases I was poking around this yesterday and noticed a few things that could be improved for our release builds: * The centos container for the x86_64 builds contained a bunch of extra tooling we no longer need such as python3 and a C++ compiler. Along with custom toolchain things this could all get removed since the C we include now is quite simple. * The aarch64 and s390x cross-compiled builds had relatively high glibc version requirements compared to the x86_64 build. This was because we don't use a container to build the cross-compiled binaries. I added containers here along the lines of the x86_64 build to use an older glibc to build the release binary to lower our version requirement. This lower the aarch64 version requirement from glibc 2.28 to 2.17. Additionally the s390x requirement dropped from 2.28 to 2.16. * To make the containers a bit easier to read/write I added `Dockerfile`s for them in a new `ci/docker` directory instead of hardcoding install commands in JS. This isn't intended to be a really big change or anything for anyone, but it's intended to keep our Linux-based builds consistent at least as best we can. * Remove temporary change

A standalone runtime for WebAssembly
A Bytecode Alliance project

Installation
The Wasmtime CLI can be installed on Linux and macOS with a small install script:
curl https://wasmtime.dev/install.sh -sSf | bash
Windows or otherwise interested users can download installers and binaries directly from the GitHub Releases page.
Example
If you've got the Rust compiler installed then you can take some Rust source code:
fn main() {
println!("Hello, world!");
}
and compile/run it with:
$ rustup target add wasm32-wasi
$ rustc hello.rs --target wasm32-wasi
$ wasmtime hello.wasm
Hello, world!
Features
-
Lightweight. Wasmtime is a standalone runtime for WebAssembly that scales with your needs. It fits on tiny chips as well as makes use of huge servers. Wasmtime can be embedded into almost any application too.
-
Fast. Wasmtime is built on the optimizing Cranelift code generator to quickly generate high-quality machine code at runtime.
-
Configurable. Whether you need to precompile your wasm ahead of time, or interpret it at runtime, Wasmtime has you covered for all your wasm-executing needs.
-
WASI. Wasmtime supports a rich set of APIs for interacting with the host environment through the WASI standard.
-
Standards Compliant. Wasmtime passes the official WebAssembly test suite, implements the official C API of wasm, and implements future proposals to WebAssembly as well. Wasmtime developers are intimately engaged with the WebAssembly standards process all along the way too.
Language Support
You can use Wasmtime from a variety of different languages through embeddings of the implementation:
- Rust - the
wasmtimecrate - C - the
wasm.h,wasi.h, andwasmtime.hheaders or usewasmtimeConan package - C++ - the
wasmtime-cpprepository or usewasmtime-cppConan package - Python - the
wasmtimePyPI package - .NET - the
WasmtimeNuGet package - Go - the
wasmtime-gorepository
