Struct Cursor 

pub struct Cursor<'a, K: TrieKey, V> { /* private fields */ }

Implementations

impl<'a, K: TrieKey, V> Cursor<'a, K, V>

pub fn current(&self) -> Option<(&[u8], &V)>

Return the key and value at the current cursor position.

pub fn current_index(&self) -> Option<usize>

Return just the key index at the current cursor position, skipping key buffer and value reads. Useful when only the position matters.

pub fn next(&mut self) -> Option<(&[u8], &V)>

Advance to the next key in sorted order, returning key and value.

pub fn prev(&mut self) -> Option<(&[u8], &V)>

Move to the previous key in sorted order, returning key and value.

pub fn next_index(&mut self) -> Option<usize>

Advance to the next key, returning only its index.

pub fn prev_index(&mut self) -> Option<usize>

Move to the previous key, returning only its index.

pub fn seek(&mut self, key: &[u8]) -> Option<(&[u8], &V)>
