Thanks for filing a feature request! Please fill out the TODOs below.

Feature

Implement core::error::Error instead of std::error::Error since MSRV > 1.81

Benefit

We can use better error handling without the std feature, i.e. in no-std environments.

Could you clarify which error impl you're interseted in? It looks like for the main Wasmtime crate core::error::Error is used, so are you looking for another crate?

It seems a few errors already use core::error::Error, but e.g. wasmtime::MemoryAccessError and wasmtime::PoolConcurrencyLimitError don't yet. There are a few references to std::error::Error in the repo, though for me wasmtime::MemoryAccessError is the one I encountered
