alexcrichton commented on issue #6669:

Could this perhaps remove the set_clocks configuration method as well? I think it could otherwise be a bit surprising that set_clocks could override set_monotonic_clock for example, but if it doesn't exist then configuration should still be possible and there shouldn't be odd interactions between methods in theory.

We should drop the WasiClocks intermediate struct entirely and just have two members of WasiCtx for the wall and monotonic clock - would you be willing to do that?

@pchickey I've renamed the traits. Unfortunately, the compiler seems to require the Send and Sync bounds. I was surprised by this as well...

@rylev The PR here is good, but separately, I'm curious; would you mind saying a little more about what your use case looks like? I'm interested in learning about who's using non-default clocks and what they're using them for.

@sunfishcode unfortunately it's not too interesting - just doing some testing around ABI conformance of wasm binaries built with old versions of wit-bindgen that have been adapted to run against the latest version of wasmtime. You can see the [code here(https://github.com/fermyon/spin-componentize/blob/d5caab107ca38a6e7adb0ff6c1cac94db73f7d36/abi-conformance/src/test_wasi.rs#L126-L138).
