Struct orga::merk::MerkStore

pub struct MerkStore<'a> { /* fields omitted */ }

A [store::Store] implementation backed by a merk Merkle key/value store.

Implementations

impl<'a> MerkStore<'a>

pub fn new(merk: &'a mut Merk) -> Self

Constructs a MerkStore which references the given Merk instance.

Trait Implementations

impl<'a> ABCIStore for MerkStore<'a>

fn height(&self) -> Result<u64>

fn root_hash(&self) -> Result<Vec<u8>>

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

Resolves a query by generating a merk proof.

fn commit(&mut self, height: u64) -> Result<()>

impl<'a> Flush for MerkStore<'a>

fn flush(&mut self) -> Result<()>

Flush is a no-op for MerkStore.

impl<'a> Read for MerkStore<'a>

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

Gets a value from the underlying Merk store.

fn wrap<T: State<Self>>(self) -> Result<T>

Wraps self with a given state::State implementation, provided for convenience.

fn into_shared(self) -> Shared<Self>

Wraps self with Shared, allowing it to be cloned so that multiple callers can share the reference to the underlying store.

fn prefix(self, prefix: u8) -> Prefixed<Self>

Wraps self with Prefixed using the given prefix byte, so that all operations have the prefix prepended to their keys.

fn into_splitter(self) -> Splitter<Self>

Wraps self with Splitter so that prefixed substores may be created by calling .split().

fn as_ref<'a>(&'a self) -> &'a Self

Returns an immutable reference to the store.

impl<'a> Write for MerkStore<'a>

fn put(&mut self, key: Vec<u8>, value: Vec<u8>) -> Result<()>

Writes a value to the underlying Merk store.

fn delete(&mut self, key: &[u8]) -> Result<()>

Deletes a value from the underlying Merk store.

fn as_mut<'a>(&'a mut self) -> &'a mut Self

Returns a mutable reference to the store.
