}

Announcement of a new channel in the network.

This message is broadcast to all nodes to inform them about a new channel. It contains the channel’s capacity, the nodes involved, and signatures.

Fields

node1_signature: Option<EcdsaSignature>

Signature from node 1

node2_signature: Option<EcdsaSignature>

Signature from node 2

ckb_signature: Option<SchnorrSignature>

Signature signed by the funding transaction output public key

features: u64

Feature flags for the channel

chain_hash: Hash256

The chain hash this channel belongs to

channel_outpoint: OutPoint

The outpoint of the funding transaction

node1_id: Pubkey

Public key of node 1

node2_id: Pubkey

Public key of node 2

ckb_key: XOnlyPublicKey

The aggregated public key of the funding transaction output

capacity: u128

The total capacity of the channel

udt_type_script: Option<Script>

UDT type script if this is a UDT channel

Implementations

impl ChannelAnnouncement

pub fn is_signed(&self) -> bool

Check if the announcement is fully signed.

pub fn out_point(&self) -> &OutPoint

Get the channel outpoint.

pub fn new_unsigned( node1_pubkey: &Pubkey, node2_pubkey: &Pubkey, channel_outpoint: OutPoint, chain_hash: Hash256, ckb_pubkey: &XOnlyPublicKey, capacity: u128, udt_type_script: Option<Script>, ) -> Self

Create an unsigned channel announcement with the given parameters.

impl ChannelAnnouncement

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

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

Trait Implementations

impl Clone for ChannelAnnouncement

fn clone(&self) -> ChannelAnnouncement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelAnnouncement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChannelAnnouncement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ChannelAnnouncement> for ChannelAnnouncement

fn from(channel_announcement: ChannelAnnouncement) -> Self

Converts to this type from the input type.

impl Hash for ChannelAnnouncement

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 ChannelAnnouncement

fn eq(&self, other: &ChannelAnnouncement) -> 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 ChannelAnnouncement

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ChannelAnnouncement> for ChannelAnnouncement

type Error = Error

The type returned in the event of a conversion error.

fn try_from( channel_announcement: ChannelAnnouncement, ) -> Result<Self, Self::Error>

Performs the conversion.
