Used to report the trie access to the TrieRecorder.

As the trie can use a TrieCache, there are multiple kinds of accesses. If a cache is used, [Self::Key] and Self::NodeOwned are possible values. Otherwise only Self::EncodedNode is a possible value.

Variants

NodeOwned

Fields

hash: H

node_owned: &'a NodeOwned<H>

The given NodeOwned was accessed using its hash.

EncodedNode

Fields

hash: H

encoded_node: Cow<'a, [u8]>

The given encoded_node was accessed using its hash.

Value

Fields

hash: H

value: Cow<'a, [u8]>

full_key: &'a [u8]

The given value was accessed using its hash.

The given full_key is the key to access this value in the trie.

Should map to RecordedForKey::Value when checking the recorder.

InlineValue

Fields

full_key: &'a [u8]

A value was accessed that is stored inline a node.

As the value is stored inline there is no need to separately record the value as it is part of a node. The given full_key is the key to access this value in the trie.

Should map to RecordedForKey::Value when checking the recorder.

Hash

Fields

full_key: &'a [u8]

The hash of the value for the given full_key was accessed.

Should map to RecordedForKey::Hash when checking the recorder.

NonExisting

Fields

full_key: &'a [u8]

The value/hash for full_key was accessed, but it couldn’t be found in the trie.

Should map to RecordedForKey::Value when checking the recorder.
