Struct Inner 

struct Inner<C: AbstractChannelFactory> {
    builder: C,
    channels: ListByRelayIds<ChannelState<C::Channel>>,
    unauth_channels: Vec<Arc<C::Channel>>,
    channels_params: ChannelParams,
    config: ChannelConfig,
    dormancy: Dormancy,
}

A map from channel id to channel state, plus necessary auxiliary state - inside lock

Fields

builder: C

The channel factory type that we store.

In this module we never use this as an AbstractChannelFactory: we just hand out clones of it when asked.

channels: ListByRelayIds<ChannelState<C::Channel>>

A map from identity to channels, or to pending channel statuses.

unauth_channels: Vec<Arc<C::Channel>>

A list of unauthenticated channels meaning they are client/bridge -> relay. We populate this list as a relay responder accepting incoming connections.

Notice here that ChannelState is NOT used because we don’t need a pending state of unauthenticated channels (inbound client/bridge) because multiple channel from the same peer can coexist. Furthermore, these channels are never looked up for normal relay operations and so a pending state is not needed.

channels_params: ChannelParams

Parameters for channels that we create, and that all existing channels are using

Will be updated by a background task, which also notifies all existing Open channels via channels.

(Must be protected by the same lock as channels, or a channel might be created using being-replaced parameters, but not get an update.)

config: ChannelConfig

The configuration (from the config file or API caller)

dormancy: Dormancy

Dormancy

The last dormancy information we have been told about and passed on to our channels. Updated via MgrState::set_dormancy and hence MgrState::reconfigure_general, which then uses it to calculate how to reconfigure the channels.
