The State Tree is the output of the execution of any operation applied on the Filecoin Blockchain. The on-chain (i.e., VM) state data structure is a map (in the form of a Hash Array Mapped Trie - HAMT) that binds addresses to actor states. The current State Tree function is called by the VM upon every actor method invocation.

type StateTree struct {
	root        adt.Map
	version     types.StateTreeVersion
	info        cid.Cid
	Store       cbor.IpldStore
	lookupIDFun func(address.Address) (address.Address, error)

	snaps *stateSnaps
}
