Trait TrieCursorFactory 

pub trait TrieCursorFactory {
    type AccountTrieCursor<'a>: TrieCursor
       where Self: 'a;
    type StorageTrieCursor<'a>: TrieStorageCursor
       where Self: 'a;

    // Required methods
    fn account_trie_cursor(
        &self,
    ) -> Result<Self::AccountTrieCursor<'_>, DatabaseError>;
    fn storage_trie_cursor(
        &self,
        hashed_address: B256,
    ) -> Result<Self::StorageTrieCursor<'_>, DatabaseError>;
}

Factory for creating trie cursors.

Required Associated Types

type AccountTrieCursor<'a>: TrieCursor where Self: 'a

The account trie cursor type.

type StorageTrieCursor<'a>: TrieStorageCursor where Self: 'a

The storage trie cursor type.

Required Methods

fn account_trie_cursor( &self, ) -> Result<Self::AccountTrieCursor<'_>, DatabaseError>

Create an account trie cursor.

fn storage_trie_cursor( &self, hashed_address: B256, ) -> Result<Self::StorageTrieCursor<'_>, DatabaseError>

Create a storage tries cursor.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
