Struct PrefixedKVStore

pub struct PrefixedKVStore<S: KVStore> { /* private fields */ }
Expand description

Wrapper that logically behaves as a key-value store whose keys are always prefixed by prefix.

Implementations§

§

impl<S: KVStore> PrefixedKVStore<S>

pub fn new(inner: S, prefix: Key) -> Self

Trait Implementations§

§

impl<S: KVStore> KVStore for PrefixedKVStore<S>

§

fn get(&self, key: Key) -> Result<Option<Value>, KVStoreError>

Retrieve the value mapped from the given key.
§

fn atomic_write<'a>( &'a self, changes: Box<dyn Iterator<Item = (Key, Option<Value>)> + 'a>, ) -> Result<(), KVStoreError>

Write a batch of updates with atomicity to the store. Any changes written should be immediately visible in Self::get.
