Crate sc_peerset

Peer Set Manager (PSM). Contains the strategy for choosing which nodes the network should be connected to.

The PSM handles sets of nodes. A set of nodes is defined as the nodes that are believed to support a certain capability, such as handling blocks and transactions of a specific chain, or collating a certain parachain.

For each node in each set, the peerset holds a flag specifying whether the node is connected to us or not.

This connected/disconnected status is specific to the node and set combination, and it is for example possible for a node to be connected through a specific set but not another.

In addition, for each, set, the peerset also holds a list of reserved nodes towards which it will at all time try to maintain a connection with.
