Struct KeyBinding

pub struct KeyBinding {
    pub chain_key: Address,
    pub packet_key: OffchainPublicKey,
    pub signature: OffchainSignature,
}

Holds the signed binding of the chain key and the packet key.

The signature is done via the offchain key to bind it with the on-chain key. The structure then makes it on-chain, making it effectively cross-signed with both keys (offchain and onchain). This is used to attest on-chain that node owns the corresponding packet key and links it with the chain key.

Fields

chain_key: Address

packet_key: OffchainPublicKey

signature: OffchainSignature

Implementations

impl KeyBinding

pub fn new(chain_key: Address, packet_key: &OffchainKeypair) -> Self

Create and sign new key binding of the given chain key and packet key.

impl KeyBinding

pub fn from_parts( chain_key: Address, packet_key: OffchainPublicKey, signature: OffchainSignature, ) -> Result<Self>

Re-construct binding from the chain key and packet key, while also verifying the given signature of the binding. Fails if the signature is not valid for the given entries.

Trait Implementations

impl Clone for KeyBinding

fn clone(&self) -> KeyBinding

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyBinding

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for KeyBinding

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for KeyBinding

fn eq(&self, other: &KeyBinding) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
