Struct Cache 

pub struct Cache<K = String, V = String>
where
    K: Clone + Eq + Hash + Send + Sync + 'static,
    V: Clone + Send + Sync + 'static,
{ /* private fields */ }

Concurrent key-value cache with named buckets.

Uses DashMap internally for lock-free concurrent reads. Create named buckets for different entity types (products, listings, etc.).

Both key and value types default to String, so Cache is a drop-in replacement for the previous untyped cache. Use Cache<i32, MyStruct>, Cache<String, Vec<u8>>, etc. for typed buckets.

Implementations

impl<K, V> Cache<K, V>

where K: Clone + Eq + Hash + Send + Sync + 'static, V: Clone + Send + Sync + 'static,

pub fn new() -> Self

pub fn with_buckets(names: &[&str]) -> Self

Create a set of named buckets upfront.

pub fn get(&self, bucket: &str, key: &K) -> Option<V>

Get a value from a named bucket.

pub fn set(&self, bucket: &str, key: K, value: V)

Set a value in a named bucket (creates the bucket if it doesn’t exist).

pub fn remove(&self, bucket: &str, key: &K) -> Option<V>

Remove a value from a named bucket.

pub fn clear_bucket(&self, bucket: &str)

Clear all entries in a specific bucket.

pub fn clear_all(&self)

Clear all buckets.
