Rust

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 Go Extension

• Wasmer Ruby Extension

• Wasmex Elixir Extension

In this section we will go through the instructions on how to setup your Rust environment, to then visit different examples of how to use Wasmer in Rust.

Published Crates

Apart from this, Wasmer publishes various other Crates:

• wasmer: The Wasmer Runtime: high level API for interacting with Wasmer
• Backends:

  • 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 (slow compilation, super fast runtime)
• 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!
