Rust - Wasmer Docs

You can use Wasmer in your Rust projects to execute WebAssembly modules securely and conveniently.
Did you know ...?
Some of our language extensions are using the Wasmer Rust crate under the hood.
​Wasmer Python Extension​
​Wasmer Ruby Extension​
​Wasmex Elixir Extension​
In this section we will go through the instructions on how to set up your Rust environment, to then visit different examples of how to use Wasmer in Rust.

Published Crates
Wasmer publishes various Crates:
​wasmer: The Wasmer Runtime
Compilers:
​wasmer-compiler-singlepass: The Singlepass compiler (fast compilation, normal runtime)
​wasmer-compiler-cranelift: The Cranelift compiler (normal compilation, a bit faster runtime)
​wasmer-compiler-llvm: The LLVM compiler (slower compilation, super fast runtime)
Engines:
​wasmer-engine-universal: The Universal Engine
​wasmer-engine-dylib: The Dynamic Library Engine
​wasmer-engine-staticlib: The Static Library Engine
Integrations:
​wasmer-wasi: Wasmer's implementation of the WASI standard. This allows you to run Wasm in a POSIX-like environment with a file system and permissions.
​wasmer-emscripten: Wasmer's implementation of the Emscripten ABI. This allows you to run Wasm in a less sandboxed way in a 32bit Linux-like environment.
Now let's setup your Rust environment!
