A proposed WebAssembly System Interface API.

This proposal currently only contains the proposed Wit interfaces with light explanation in comments; more work is necessary to fully document the proposal. The Wit comments annotate where the proposed interface is expected to change in the short term (for Preview2) once resources and handles are re-added to Wit, and then after that (for Preview3) once native stream support is added to the Component Model and Wit.

The wit directory currently validates and can generate bindings with:

wit-bindgen c wit/ --world proxy

or can be manipulated in other ways with:

wasm-tools component wit wit/ ...

The wit/deps directory contains a live snapshot of the contents of several other WASI proposals upon which this proposal depends. It is automatically updated by running wit-deps update in the root directory, which fetches the live contents of the main branch of each proposal. As things stablize, wit/deps.toml will be updated to refer to versioned releases.

wasi-http is currently in Phase 1.

This readme needs to be expanded to cover a number of additional fields suggested in the WASI Proposal template.
