About sandboxing

This is probably a stupid question so bear with me, when you say that Wasmer can run untrusted code... what limitations are on that code? For example, would I be able to run code on wasmer that reads or edits files from the file system?

Wasmer Aarch64 Support

It appears at one time there was a Aarch64 backend added for the Singlepass backend. I can no longer find the code in github. Can you tell me what the state of Aarch64 code generation support is?

Embedding wasmer-compiled native module in Rust

Hello! I'm new to WASM. I tried out wasmer v1.0.0-alpha3, native mode with llvm backend and it looks great! I've run bzip2, mcf, libquantum, and astar from SPEC2006 integer benchmarks and it shows only 10%, -30%, 7%, 9% overhead compared to the native executable compiled with…
