Struct Capability 

pub struct Capability {
    pub signer: Address,
    pub spending_cap: u64,
    pub pool_id: B256,
    pub expiry: u64,
}

A pool owner’s spending grant in its unsigned form.

Fields

signer: Address

The address the owner delegates spend to — the voucher-signing key.

spending_cap: u64

Maximum cumulative amount (token base units) the signer may spend against pool_id under this grant. A u64 to match the PaymentPool.spendingCap storage/calldata width exactly; the EIP-712 type-string still hashes it as a uint256 word (the signing hash widens it with U256::from).

pool_id: B256

The pool this capability draws from — the on-chain PaymentPool deposit id.

expiry: u64

Unix-seconds expiry. After it, vouchers under this capability are no longer redeemable and the node stops accepting them.

Implementations

impl Capability

pub fn signing_hash(&self, domain: &Eip712Domain) -> B256

EIP-712 signing hash bound to domain — the 32-byte digest the contract recovers the owner signature against.

pub fn sign<S: SignerSync>( self, signer: &S, domain: &Eip712Domain, ) -> Result<SignedCapability, Error>

Sign the capability with the pool owner’s signer for the given EIP-712 domain.

Errors

Propagates any error returned by the underlying signer (key locked, remote signer offline, etc.).
