Struct ChannelConfig

pub struct ChannelConfig {
    pub forwarding_fee_proportional_millionths: u32,
    pub forwarding_fee_base_msat: u32,
    pub cltv_expiry_delta: u16,
    pub max_dust_htlc_exposure: MaxDustHTLCExposure,
    pub force_close_avoidance_max_fee_satoshis: u64,
    pub accept_underpaying_htlcs: bool,
}

Options which apply on a per-channel basis and may change at runtime or based on negotiation with our counterparty.

Fields

forwarding_fee_proportional_millionths: u32

Amount (in millionths of a satoshi) charged per satoshi for payments forwarded outbound over the channel. This may be allowed to change at runtime in a later update, however doing so must result in update messages sent to notify all nodes of our updated relay fee.

Please refer to LdkChannelConfig for further details.

forwarding_fee_base_msat: u32

Amount (in milli-satoshi) charged for payments forwarded outbound over the channel, in excess of ChannelConfig::forwarding_fee_proportional_millionths. This may be allowed to change at runtime in a later update, however doing so must result in update messages sent to notify all nodes of our updated relay fee.

Please refer to LdkChannelConfig for further details.

cltv_expiry_delta: u16

The difference in the CLTV value between incoming HTLCs and an outbound HTLC forwarded over the channel this config applies to.

Please refer to LdkChannelConfig for further details.

max_dust_htlc_exposure: MaxDustHTLCExposure

Limit our total exposure to potential loss to on-chain fees on close, including in-flight HTLCs which are burned to fees as they are too small to claim on-chain and fees on commitment transaction(s) broadcasted by our counterparty in excess of our own fee estimate.

Please refer to LdkChannelConfig for further details.

force_close_avoidance_max_fee_satoshis: u64

The additional fee we’re willing to pay to avoid waiting for the counterparty’s to_self_delay to reclaim funds.

Please refer to LdkChannelConfig for further details.

accept_underpaying_htlcs: bool

If set, allows this channel’s counterparty to skim an additional fee off this node’s inbound HTLCs. Useful for liquidity providers to offload on-chain channel costs to end users.

Please refer to LdkChannelConfig for further details.

Trait Implementations

impl Clone for ChannelConfig

fn clone(&self) -> ChannelConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelConfig

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

Formats the value using the given formatter.

impl Default for ChannelConfig

fn default() -> Self

Returns the “default value” for a type.

impl From<ChannelConfig> for ChannelConfig

fn from(value: LdkChannelConfig) -> Self

Converts to this type from the input type.

impl From<ChannelConfig> for ChannelConfig

fn from(value: ChannelConfig) -> Self

Converts to this type from the input type.

impl PartialEq for ChannelConfig

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