Struct lightning::util::config::UserConfig

pub struct UserConfig {
    pub channel_handshake_config: ChannelHandshakeConfig,
    pub channel_handshake_limits: ChannelHandshakeLimits,
    pub channel_config: ChannelConfig,
    pub accept_forwards_to_priv_channels: bool,

}

Top-level config which holds ChannelHandshakeLimits and ChannelConfig.

Default::default() provides sane defaults for most configurations (but currently with 0 relay fees!)

Fields

channel_handshake_config: ChannelHandshakeConfig

Channel handshake config that we propose to our counterparty.

channel_handshake_limits: ChannelHandshakeLimits

Limits applied to our counterparty’s proposed channel handshake config settings.

channel_config: ChannelConfig

Channel config which affects behavior during channel lifetime.

accept_forwards_to_priv_channels: bool

If this is set to false, we will reject any HTLCs which were to be forwarded over private channels. This prevents us from taking on HTLC-forwarding risk when we intend to run as a node which is not online reliably.

For nodes which are not online reliably, you should set all channels to not be announced (using ChannelHandshakeConfig::announced_channel and ChannelHandshakeLimits::force_announced_channel_preference) and set this to false to ensure you are not exposed to any forwarding risk.

Note that because you cannot change a channel’s announced state after creation, there is no way to disable forwarding on public channels retroactively. Thus, in order to change a node from a publicly-announced forwarding node to a private non-forwarding node you must close all your channels and open new ones. For privacy, you should also change your node_id (swapping all private and public key material for new ones) at that time.

Default value: false.

accept_inbound_channels: bool

If this is set to false, we do not accept inbound requests to open a new channel. Default value: true.

manually_accept_inbound_channels: bool

If this is set to true, the user needs to manually accept inbound requests to open a new channel.

When set to true, Event::OpenChannelRequest will be triggered once a request to open a new inbound channel is received through a msgs::OpenChannel message. In that case, a msgs::AcceptChannel message will not be sent back to the counterparty node unless the user explicitly chooses to accept the request.

Default value: false.
