Struct SignedCapability 

pub struct SignedCapability {
    pub capability: Capability,
    pub signature: Signature,
}

A capability together with its EIP-712 owner signature.

Fields

capability: Capability

The delegation itself.

signature: Signature

The pool owner’s EIP-712 signature over it.

Implementations

impl SignedCapability

pub fn recover_owner( &self, domain: &Eip712Domain, ) -> Result<Address, CapabilityError>

Recover the owner address that signed this capability under domain.

Errors

Returns CapabilityError::InvalidSignature if the signature is malformed (non-canonical high-s, invalid recovery id, etc.) — rejecting high-s up front so the off-chain accept-set matches the on-chain verifiable-set (#836), exactly as voucher recovery does.

pub fn verify_owner( &self, expected: Address, domain: &Eip712Domain, ) -> Result<(), CapabilityError>

Verify the capability was signed by expected (the pool owner) for domain.

Errors

• CapabilityError::InvalidSignature — signature is malformed.
• CapabilityError::WrongOwner — recovered address differs from expected.
