Struct permitCall 

pub struct permitCall {
    pub owner: Address,
    pub spender: Address,
    pub value: U256,
    pub deadline: U256,
    pub v: u8,
    pub r: FixedBytes<32>,
    pub s: FixedBytes<32>,
}

@dev Sets value as the allowance of spender over owner’s tokens, given owner’s signed approval.

IMPORTANT: The same issues {IERC20-approve} has related to transaction ordering also apply here.

Emits an {Approval} event.

Requirements:

• spender cannot be the zero address.
• deadline must be a timestamp in the future.
• v, r and s must be a valid secp256k1 signature from owner over the EIP712-formatted function arguments.
• the signature must use owner’s current nonce (see {nonces}).

For more information on the signature format, see the https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP section]. Function with signature permit(address,address,uint256,uint256,uint8,bytes32,bytes32) and selector 0xd505accf.

function permit(address owner, address spender, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external;

Fields

owner: Address

spender: Address

value: U256

deadline: U256

v: u8

r: FixedBytes<32>

s: FixedBytes<32>
