Struct MemoryStore 

pub struct MemoryStore { /* private fields */ }

A thread-safe in-memory cache store backed by DashMap.

Implementations

impl MemoryStore

pub fn new() -> Self

Creates an empty memory store.

pub fn read_with_options( &self, key: &str, options: &CacheOptions, ) -> Option<Value>

Reads a cached value using explicit options such as version matching.

pub fn exist_with_options(&self, key: &str, options: &CacheOptions) -> bool

Returns true when a live entry exists for key under the given options.

Trait Implementations

impl CacheStore for MemoryStore

fn read(&self, key: &str) -> Option<Value>

Reads a cached value for key.

fn write(&self, key: &str, value: Value, options: CacheOptions)

Writes a value under key with the given options.

fn delete(&self, key: &str) -> bool

Deletes key, returning true when an entry existed.

fn exist(&self, key: &str) -> bool

Returns true when a live entry exists for key.

fn fetch( &self, key: &str, options: CacheOptions, f: impl FnOnce() -> Value, ) -> Value

Reads a cached value or computes and stores it on a miss.

fn increment(&self, key: &str, amount: i64) -> Option<i64>

Increments an integer entry by amount.

fn decrement(&self, key: &str, amount: i64) -> Option<i64>

Decrements an integer entry by amount.

fn clear(&self)

Removes all entries from the store.

fn read_multi(&self, keys: &[&str]) -> HashMap<String, Value>

Reads many keys at once, omitting misses.

fn write_multi(&self, entries: HashMap<String, Value>, options: CacheOptions)

Writes many key/value pairs with shared options.

impl Debug for MemoryStore

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

Formats the value using the given formatter.

impl Default for MemoryStore

fn default() -> MemoryStore

Returns the “default value” for a type.
