Struct orga::abci::MemStore

pub struct MemStore { /* fields omitted */ }

A basic implementation of ABCIStore which persists data in memory (mostly for use in testing).

Implementations

impl MemStore

pub fn new() -> Self

Trait Implementations

impl ABCIStore for MemStore

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

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

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

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

impl Read for MemStore

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

Gets a value by key.

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 Write for MemStore

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

Writes a key and value to the store.

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

Deletes the value with the given key.

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

Returns a mutable reference to the store.
