We already test that the crate compiles against wasm32: https://github.com/sfackler/rust-postgres/blob/master/.github/workflows/ci.yml#L50-L75.
If tokio gains direct wasm32 support I'd be happy to expand the supported feature set here, but I don't want to make changes that only work when building against an unspecified tokio fork.
This is not specific to a particular tokio; it’s just that this crate does not define KeepaliveConfig in wasm32. I’ve ignored all references to KeepaliveConfig in wasm32, and I believe these changes are reasonable.
The runtime
Cargo feature is not supported on wasm32 at this time, and can't be without changes to tokio.
I am pretty sure that my changes work with standard tokio. Your CI still passes with this PR.
In this line, the parameter KeepaliveConfig is ignored when compiled to wasm32, while there is no corresponding conditional compilation elsewhere. Therefore, I added a conditional compilation for wasm32 in the places where Keepalive is needed. This modification allows the crate to be used normally in wasm32 after replacing the underlying tokio with a patch.
