An open_channel message to be sent or received from a peer

Fields

chain_hash: BlockHash

The genesis hash of the blockchain where the channel is to be opened

temporary_channel_id: [u8; 32]

A temporary channel ID, until the funding outpoint is announced

funding_satoshis: u64

The channel value

push_msat: u64

The amount to push to the counterparty as part of the open, in milli-satoshi

dust_limit_satoshis: u64

The threshold below which outputs on transactions broadcast by sender will be omitted

max_htlc_value_in_flight_msat: u64

The maximum inbound HTLC value in flight towards sender, in milli-satoshi

channel_reserve_satoshis: u64

The minimum value unencumbered by HTLCs for the counterparty to keep in the channel

htlc_minimum_msat: u64

The minimum HTLC size incoming to sender, in milli-satoshi

feerate_per_kw: u32

The feerate per 1000-weight of sender generated transactions, until updated by update_fee

to_self_delay: u16

The number of blocks which the counterparty will have to wait to claim on-chain funds if they broadcast a commitment transaction

max_accepted_htlcs: u16

The maximum number of inbound HTLCs towards sender

funding_pubkey: PublicKey

The sender’s key controlling the funding transaction

revocation_basepoint: PublicKey

Used to derive a revocation key for transactions broadcast by counterparty

payment_point: PublicKey

A payment key to sender for transactions broadcast by counterparty

delayed_payment_basepoint: PublicKey

Used to derive a payment key to sender for transactions broadcast by sender

htlc_basepoint: PublicKey

Used to derive an HTLC payment key to sender

first_per_commitment_point: PublicKey

The first to-be-broadcast-by-sender transaction’s per commitment point

channel_flags: u8

Channel flags

shutdown_scriptpubkey: OptionalField<Script>

Optionally, a request to pre-set the to-sender output’s scriptPubkey for when we collaboratively close

Trait Implementations

impl Clone for OpenChannel

fn clone(&self) -> OpenChannel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpenChannel

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

Formats the value using the given formatter.

impl PartialEq<OpenChannel> for OpenChannel

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Readable for OpenChannel

fn read<R: Read>(r: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read

impl Writeable for OpenChannel

fn write<W: Writer>(&self, w: &mut W) -> Result<(), Error>

Writes self out to the given Writer

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec

fn encode_with_len(&self) -> Vec<u8>

Writes self out to a Vec

impl StructuralPartialEq for OpenChannel
