@zerosnacks I'd like to take this on. Do you have any suggestions for an optimal example for each type?

Thanks! The goal of the example is to clarify to users when you should use each type and how they are different from each other. For the vast majority of cases users should always use the sol! macro so this is an advanced use case. For inspiration have a look through the codebase of each crate. The result can be three different examples or just one example. A reference could be how we should different parts of working with big numbers: https://github.com/alloy-rs/examples/tree/main/examples/big-numbers/examples

Hi @PraneshASP let me know if you are running into any issues or need any pointers, happy to help!

[PraneshASP]

Hi @zerosnacks sorry caught up with other things, I'm looking into adding examples now!

[zerosnacks]

No problem! Thanks

[PraneshASP]

Added example for dyn_abi encoding. Initial feedback would be appreciated :)) @zerosnacks TIA!

[PraneshASP]

Added example for sol!() macro as well.

Example for json ABI encoding is left. It looks like there's no encode/decode method implemented in the json-abi crate? ethabi implements it tho. Am I missing something?

I think ABI decoding should be sufficient here for the json-abi crate as shown here: https://github.com/alloy-rs/core/blob/main/crates/json-abi/tests/it/abis.rs

It would be nice to combine the various test cases into a single one covering the constructor, a function, an event and an error?
