Expand description

Variants§

§

Value

We recorded all trie nodes up to the value for a storage key.

This should be returned when the recorder has seen the following TrieAccess:

§

Hash

We recorded all trie nodes up to the value hash for a storage key.

If we have a RecordedForKey::Value, it means that we also have the hash of this value. This also means that if we first have recorded the hash of a value and then also record the value, the access should be upgraded to RecordedForKey::Value.

This should be returned when the recorder has seen the following TrieAccess:

§

None

We haven’t recorded any trie nodes yet for a storage key.

This means we have not seen any TrieAccess referencing the searched key.

impl PartialEq for RecordedForKey

source§

fn eq(&self, other: &RecordedForKey) -> bool
