The public key of the node

version: String

Software version string

node_name: AnnouncedNodeName

Human-readable node name (up to 32 bytes)

addresses: Vec<Multiaddr>

Reachable addresses for this node

chain_hash: Hash256

The chain hash this node is on

auto_accept_min_ckb_funding_amount: u64

Implementations

impl NodeAnnouncement

pub fn new_unsigned( node_name: AnnouncedNodeName, features: FeatureVector, addresses: Vec<Multiaddr>, node_id: Pubkey, chain_hash: Hash256, timestamp: u64, auto_accept_min_ckb_funding_amount: u64, udt_cfg_infos: UdtCfgInfos, version: String, ) -> Self

Create an unsigned node announcement with the given parameters.

The udt_cfg_infos and version are passed as parameters to avoid depending on runtime/global state from the caller’s crate.

pub fn new_signed( node_name: AnnouncedNodeName, features: FeatureVector, addresses: Vec<Multiaddr>, private_key: &Privkey, chain_hash: Hash256, timestamp: u64, auto_accept_min_ckb_funding_amount: u64, udt_cfg_infos: UdtCfgInfos, version: String, ) -> Self

Create a signed node announcement.

Builds an unsigned announcement, signs it with the given private key, and returns the signed announcement.

pub fn message_to_sign(&self) -> [u8; 32]

Get the message bytes to sign (hash of unsigned molecule serialization).

pub fn cursor(&self) -> Cursor

Get the cursor for this node announcement.

pub fn verify(&self) -> bool

Verify the signature on this announcement.

Trait Implementations

impl Clone for NodeAnnouncement

fn clone(&self) -> NodeAnnouncement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeAnnouncement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeAnnouncement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<NodeAnnouncement> for NodeAnnouncement

fn from(node_announcement: NodeAnnouncement) -> Self

Converts to this type from the input type.

impl Hash for NodeAnnouncement

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeAnnouncement

fn eq(&self, other: &NodeAnnouncement) -> 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.

impl Serialize for NodeAnnouncement

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<NodeAnnouncement> for NodeAnnouncement

type Error = Error

The type returned in the event of a conversion error.

fn try_from(node_announcement: NodeAnnouncement) -> Result<Self, Self::Error>

Performs the conversion.
