You're welcome to continue experimenting with this, but there's no point in merging this until it's stabilized as a target for |
Totally fair, I understand it’s still experimental. The WASI Preview 3 target (wasm32-wasip3) is expected to land in the next Rust release or just after that (most probably), but for now I’m using wasm32-wasip2 as the dev target to keep things working. It’s mostly exploratory right now, but it does feel like something that’ll be quite useful once stabilized. |

@abonander Would it be alright to keep this PR open as a reference while I continue experimenting, or would you prefer I link to my fork in the relevant issue and close this PR to keep the list clean? |

Does your PR solve an issue?
closes #4056
Is this a breaking change?
No, New runtime would run separately, conditional compilation ensures that.
Limitations
This PR adds wasm32 target support for non-TLS backends only (for now since wasi-tls is in phase 1). Some stubs are intentionally left open for further development such as
sqlx-core/src/wasm/fs.rsto support future wasi-native file system certificate actions.
