Contains fields that are both common to open_channel and open_channel2 messages.

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 For V2 channels: derived using a zeroed out value for the channel acceptor’s revocation basepoint For V1 channels: a temporary channel ID, until the funding outpoint is announced

funding_satoshis: u64

For V1 channels: The channel value For V2 channels: 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

commitment_feerate_sat_per_1000_weight: u32

The feerate for the commitment transaction set by the channel initiator until updated by UpdateFee

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

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

channel_flags: u8

The channel flags to be used

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<Features<ChannelTypeContext>>

The channel type that this channel will represent

If this is None, we derive the channel type from the intersection of our feature bits with our counterparty’s feature bits from the Init message.

Implementations

impl CommonOpenChannelFields

pub fn channel_parameters(&self) -> ChannelParameters

The ChannelParameters for this channel.

Trait Implementations

impl Clone for CommonOpenChannelFields

fn clone(&self) -> CommonOpenChannelFields

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CommonOpenChannelFields

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

Formats the value using the given formatter.

impl Hash for CommonOpenChannelFields

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

where __H: Hasher,

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 CommonOpenChannelFields

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