Dynamically decoding response based on user-provided type

Question

In Solidity, I want users to provide the Solidity type of a response upfront, and when the response arrives, I want to decode it based on the type that the user provided - basically dynamic decoding of sorts.

You can imagine something like:

abi.decode(responseData, (userProvidedType));

Is there an elegant way of doing this?

unfortunately not. You usually have to have a giant if/else handler. You can also have different functions that take different types like hardhat's console (https://github.com/NomicFoundation/hardhat/blob/main/packages/hardhat-core/console.sol). eg:

function a(uint) {}

function a(address){}
