Trait reth_trie::hashed_cursor::HashedCursor

pub trait HashedCursor {
    type Value: Debug;

    // Required methods
    fn seek(
        &mut self,
        key: B256,
    ) -> Result<Option<(B256, Self::Value)>, DatabaseError>;
    fn next(&mut self) -> Result<Option<(B256, Self::Value)>, DatabaseError>;
}

The cursor for iterating over hashed entries.

Required Associated Types

type Value: Debug

Value returned by the cursor.

Required Methods

fn seek( &mut self, key: B256, ) -> Result<Option<(B256, Self::Value)>, DatabaseError>

Seek an entry greater or equal to the given key and position the cursor there. Returns the first entry with the key greater or equal to the sought key.

fn next(&mut self) -> Result<Option<(B256, Self::Value)>, DatabaseError>

Move the cursor to the next entry and return it.
