Struct LocalKv 

pub struct LocalKv { /* private fields */ }

Implementations

impl LocalKv

pub async fn new(data_dir: PathBuf) -> Result<Self>

pub fn data_dir(&self) -> &PathBuf

Get the data directory path (the directory that holds localkv.sqlite).

pub async fn len(&self) -> Result<usize>

Get the number of items currently stored (including expired items). Useful for testing.

pub async fn is_empty(&self) -> Result<bool>

Check if the store is empty (including expired items). Useful for testing.

pub async fn clear(&self) -> Result<()>

Clear all data from the store. Useful for testing.

pub async fn keys(&self) -> Result<Vec<String>>

Get all keys currently in the store (including expired ones). Useful for testing and debugging.

Trait Implementations

impl Binding for LocalKv

impl Debug for LocalKv

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

Formats the value using the given formatter.

impl Kv for LocalKv

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get a value by key. Returns None if key doesn’t exist or has expired.

fn put<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Vec<u8>, options: Option<PutOptions>, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Put a value with optional options. When options.if_not_exists is true, returns true if created, false if already exists. When options.if_not_exists is false or options is None, always returns true.

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete a key. No error if key doesn’t exist.

fn exists<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if a key exists without retrieving the value.

fn scan_prefix<'life0, 'life1, 'async_trait>( &'life0 self, prefix: &'life1 str, limit: Option<usize>, cursor: Option<String>, ) -> Pin<Box<dyn Future<Output = Result<ScanResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Scan keys with a prefix, with pagination support.
