Struct PermitSingle

Source

pub struct PermitSingle { /* private fields */ }

Expand description

A single Permit2 authorization, covering one token for one spender.

Implementations§

Source §

impl PermitSingle

Source

pub fn new( details: PermitDetails, spender: Bytes, sig_deadline: BigUint, ) -> Self

Source

pub fn eip712_signing_hash( &self, chain_id: u64, permit2_address: &Bytes, ) -> Result<[u8; 32], FyndError>

Compute the Permit2 EIP-712 signing hash for this permit.

Pass the returned bytes to your signer’s sign_hash method, then supply the 65-byte result as the signature argument to EncodingOptions::with_permit2.

permit2_address must be the 20-byte address of the Permit2 contract (canonical cross-chain deployment: 0x000000000022D473030F116dDEE9F6B43aC78BA3).

§Errors

Returns crate::FyndError::Protocol if any address field is not exactly 20 bytes, or if amount / expiration / nonce exceed their respective Solidity types.
