@dev Interface of the ERC20 Permit extension allowing approvals to be made via signatures, as defined in\n https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].\n Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by\n presenting a message signed by the account.

Tokens that return no value (and instead revert or throw on failure) are also supported, non-reverting calls are assumed to be successful. To use this library you can add a `using SafeERC20 for IERC20;` statement to your contract, which allows you to call the safe operations as `token.safeTransfer(...)`,
