}

An open_channel2 message to be sent by or received from the channel initiator.

Used in V2 channel establishment

Fields

chain_hash: ChainHash

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

temporary_channel_id: ChannelId

A temporary channel ID derived using a zeroed out value for the channel acceptor’s revocation basepoint

funding_feerate_sat_per_1000_weight: u32

The feerate for the funding transaction set by the channel initiator

commitment_feerate_sat_per_1000_weight: u32

The feerate for the commitment transaction set by the channel initiator

funding_satoshis: u64

Part of the channel value contributed by the channel initiator

dust_limit_satoshis: u64

The threshold below which outputs on transactions broadcast by the channel initiator will be omitted

max_htlc_value_in_flight_msat: u64

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

htlc_minimum_msat: u64

The minimum HTLC size incoming to channel initiator, in milli-satoshi

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 channel initiator

locktime: u32

The locktime for the funding transaction

funding_pubkey: PublicKey

The channel initiator’s key controlling the funding transaction

revocation_basepoint: PublicKey

Used to derive a revocation key for transactions broadcast by counterparty

payment_basepoint: PublicKey

A payment key to channel initiator for transactions broadcast by counterparty

delayed_payment_basepoint: PublicKey

Used to derive a payment key to channel initiator for transactions broadcast by channel initiator

htlc_basepoint: PublicKey

Used to derive an HTLC payment key to channel initiator

first_per_commitment_point: PublicKey

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

second_per_commitment_point: PublicKey

The second to-be-broadcast-by-channel-initiator transaction’s per commitment point

channel_flags: u8

Channel flags

shutdown_scriptpubkey: Option<ScriptBuf>

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

channel_type: Option<ChannelTypeFeatures>

The channel type that this channel will represent. If none is set, we derive the channel type from the intersection of our feature bits with our counterparty’s feature bits from the Init message.

require_confirmed_inputs: Option<()>

Optionally, a requirement that only confirmed inputs can be added

Trait Implementations

impl Clone for OpenChannelV2

fn clone(&self) -> OpenChannelV2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpenChannelV2

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

Formats the value using the given formatter.

impl Hash for OpenChannelV2

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 OpenChannelV2

fn eq(&self, other: &OpenChannelV2) -> bool

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

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

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

impl Readable for OpenChannelV2

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

Reads a Self in from the given Read.

impl Writeable for OpenChannelV2

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

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

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.

impl Eq for OpenChannelV2
