How to use decodeAbiParameters on a tuple?

I've been trying to transition from ethers to viem, but still wasn't able to figure out the best way to use decodeAbiParameters on a tuple.

So, how can I convert this function to viem?

const abiCoder: AbiCoder = AbiCoder.defaultAbiCoder()

function decodeDeploymentConfig(input: string): DeploymentConfig {
  const decodedConfig = abiCoder.decode(
    [
      'tuple(bytes32 contractType, uint32 chainType, bytes32 salt, bytes byteCode, bytes initCode) config',
      'tuple(bytes32 r, bytes32 s, uint8 v) signature',
      'address signer',
    ],
    input,
  )

  return {
    config: {
      contractType: decodedConfig.config.contractType,
      chainType: decodedConfig.config.chainType,
      salt: decodedConfig.config.salt,
      byteCode: decodedConfig.config.byteCode,
      initCode: decodedConfig.config.initCode,
    },
    signature: {
      r: decodedConfig.signature.r,
      s: decodedConfig.signature.s,
      v: decodedConfig.signature.v,
    },
    signer: decodedConfig.signer,
  }
}

const [config, signature, signer] = decodeAbiParameters(
  parseAbiParameters([
    '(bytes32 contractType, uint32 chainType, bytes32 salt, bytes byteCode, bytes initCode) config',
    '(bytes32 r, bytes32 s, uint8 v) signature',
    'address signer',
  ]),
  input,
)

return { config, signature, signer }

should work

Thank you very much! It does work, but looks like there's a bug with the inference for the return type.

It would be nice to have an example like this in the docs.
