This repo will ultimately serve as a library providing a common implementation of WASI hostcalls for re-use in any WASI (and potentially non-WASI) runtimes such as [Wasmtime] and [Lucet].
The library is an adaption of [lucet-wasi] crate from the [Lucet] project, and it is currently based on 40ae1df git revision.
Please note that the library requires Rust compiler version at least 1.36.0.
In our *nix implementation, we currently support the entire [WASI API]
with the exception of socket hostcalls:
- sock_recv
- sock_send
- sock_shutdown
We expect these to be implemented when network access is standardised.
We also currently do not support the proc_raise hostcall, as it is expected to
be dropped entirely from WASI.
In our Windows implementation, we currently support the minimal subset of [WASI API] which allows for running the very basic "Hello world!" style WASM apps. More coming shortly, so stay tuned!
Significant parts of our hostcall implementations are derived from the C implementations in
cloudabi-utils. See LICENSE.cloudabi-utils for license information.
