Storage Trie Writer

Required Methods

fn write_storage_trie_updates_sorted<'a>( &self, storage_tries: impl Iterator<Item = (&'a FixedBytes<32>, &'a StorageTrieUpdatesSorted)>, ) -> Result<usize, ProviderError>

Writes storage trie updates from the given storage trie map with already sorted updates.

Expects the storage trie updates to already be sorted by the hashed address key.

Returns the number of entries modified.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
