/**
* Calculates an Ethereum-specific signature in [EIP-191 format](https://eips.ethereum.org/EIPS/eip-191): `keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))`.
*
* - Docs: https://viem.sh/docs/actions/wallet/signMessage
* - JSON-RPC Methods:
* - JSON-RPC Accounts: [`personal_sign`](https://docs.metamask.io/guide/signing-data#personal-sign)
* - Local Accounts: Signs locally. No JSON-RPC request.
*
* With the calculated signature, you can:
* - use [`verifyMessage`](https://viem.sh/docs/utilities/verifyMessage) to verify the signature,
* - use [`recoverMessageAddress`](https://viem.sh/docs/utilities/recoverMessageAddress) to recover the signing address from a signature.
*
* @param client - Client to use
* @param parameters - {@link SignMessageParameters}
* @returns The signed message. {@link SignMessageReturnType}
*
* @example
* import { createWalletClient, custom } from 'viem'
* import { mainnet } from 'viem/chains'
* import { signMessage } from 'viem/wallet'
*
* const client = createWalletClient({
* chain: mainnet,
* transport: custom(window.ethereum),
* })
* const signature = await signMessage(client, {
* account: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
* message: 'hello world',
* })
*
* @example
* // Account Hoisting
* import { createWalletClient, custom } from 'viem'
* import { privateKeyToAccount } from 'viem/accounts'
* import { mainnet } from 'viem/chains'
* import { signMessage } from 'viem/wallet'
*
* const client = createWalletClient({
* account: privateKeyToAccount('0x…'),
* chain: mainnet,
* transport: custom(window.ethereum),
* })
* const signature = await signMessage(client, {
* message: 'hello world',
* })
