Represents access to immutable merkle tree nodes.

Required Methods

fn get_node(&self, id: &TreeID) -> Result<N, Error>

Gets an intermediate Node by its TreeID.

fn set_node(&mut self, id: TreeID, node: N) -> Result<(), Error>

Stores an intermediate Node by its TreeID.

fn get_leaf(&self, id: &TreeID) -> Result<N, Error>

Gets a leaf Node by its TreeID.

fn set_leaf(&mut self, id: TreeID, leaf: N) -> Result<(), Error>

Stores a leaf Node by its TreeID.

Provided Methods

fn get(&self, id: &TreeID) -> Result<N, Error>

Gets a Node by its TreeID.

fn set(&mut self, id: TreeID, node: N) -> Result<(), Error>

Stores a Node by its TreeID.

fn get_many<'a, I: Iterator<Item = TreeID>>( &self, ids: I, ) -> Result<BTreeMap<TreeID, N>, Error>

Gets many Nodes from an Iterator of TreeIDs.

fn set_many<I: Iterator<Item = (TreeID, N)>>( &mut self, nodes: I, ) -> Result<(), Error>

Sets many Nodes from an Iterator of TreeIDs and Nodes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
