source · pub struct MemoryNetwork<K: SignatureKey> {
inner: Arc<MemoryNetworkInner<K>>,
}
Expand description
In memory only network simulator.
This provides an in memory simulation of a networking implementation, allowing nodes running on the same machine to mock networking while testing other functionality.
Under the hood, this simply maintains mpmc channels to every other MemoryNetwork
insane of the
same group.
Fields§
§inner: Arc<MemoryNetworkInner<K>>
The actual internal state
