Overview

Package state_native defines how the beacon chain state for Ethereum functions in the running beacon node, using an advanced, immutable implementation of the state data structure.

BeaconState getters may be accessed from inside or outside the package. To avoid duplicating locks, we have internal and external versions of the getter. The external function obtains a read lock, then calls the internal function. The internal function returns the required data without further locking, allowing it to be used by other package-level functions that already hold a lock. Hence the functions look something like this: 

func (b *BeaconState) Foo() uint64 {
  // Read lock.
  b.lock.RLock()
  defer b.lock.RUnlock()

  // Internal getter.
  return b.foo()
}

func (b *BeaconState) foo() uint64 {
  (...) // Some processing logic.

  return b.foo
}

Although it is technically possible to remove the short-circuit conditions from the external function, that would require every read to obtain a lock even if the data was not present, leading to potential slowdowns.
