Required Methods§

source

fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>>

Fetch entry with given key.

source

fn get_proof(&self, key: &[u8]) -> Result<Option<Proof>>

Fetch proof for entry with given key.

source

fn prefetch_prefixes(&self, prefixes: &[Prefix], limit: u16) -> Result<()>

Populate the in-memory tree with nodes for keys starting with given prefixes.

source

fn iter(&self) -> Box<dyn Iterator + '_>

Returns an iterator over the tree.
