Struct monotree::tree::Monotree

pub struct Monotree<D = DefaultDatabase, H = DefaultHasher> { /* private fields */ }

A structure for monotree.

Implementations

impl<D, H> Monotree<D, H>where D: Database, H: Hasher,

pub fn new(dbpath: &str) -> Self

pub fn insert( &mut self, root: Option<&Hash>, key: &Hash, leaf: &Hash ) -> Result<Option<Hash>>

Insert key-leaf entry into the monotree. Returns a new root hash.

pub fn get(&mut self, root: Option<&Hash>, key: &Hash) -> Result<Option<Hash>>

Get a leaf hash for the given root and key.

pub fn remove( &mut self, root: Option<&Hash>, key: &[u8] ) -> Result<Option<Hash>>

Remove the given key and its corresponding leaf from the tree. Returns a new root hash.

pub fn inserts( &mut self, root: Option<&Hash>, keys: &[Hash], leaves: &[Hash] ) -> Result<Option<Hash>>

This method is intended to use the insert() method in batch mode.

pub fn gets( &mut self, root: Option<&Hash>, keys: &[Hash] ) -> Result<Vec<Option<Hash>>>

This method is intended to use the get() method in batch mode.

pub fn removes( &mut self, root: Option<&Hash>, keys: &[Hash] ) -> Result<Option<Hash>>

This method is intended to use the remove() method in batch mode.

pub fn get_merkle_proof( &mut self, root: Option<&Hash>, key: &[u8] ) -> Result<Option<Proof>>

Generate a Merkle proof for the given root and key.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Monotree<DefaultDatabase, DefaultHasher>

fn default() -> Self
