Struct sp_trie::recorder::Recorder

impl<H: Hasher> Recorder<H>

pub fn as_trie_recorder(&self) -> impl TrieRecorder<H::Out> + '_

Returns the recorder as TrieRecorder compatible type.

pub fn drain_storage_proof(self) -> StorageProof

Drain the recording into a StorageProof.

While a recorder can be cloned, all share the same internal state. After calling this function, all other instances will have their internal state reset as well.

If you don’t want to drain the recorded state, use Self::to_storage_proof.

Returns the StorageProof.

pub fn to_storage_proof(&self) -> StorageProof

Convert the recording to a StorageProof.

In contrast to Self::drain_storage_proof this doesn’t consumes and doesn’t clears the recordings.

Returns the StorageProof.

pub fn estimate_encoded_size(&self) -> usize

Returns the estimated encoded size of the proof.

The estimation is based on all the nodes that were accessed until now while accessing the trie.

pub fn reset(&self)

Reset the state.

This discards all recorded data.
