Struct InMemoryStateStore 

pub struct InMemoryStateStore { /* private fields */ }

Default in-process backend backed by a lock-free HopscotchMap. Suitable for single-process deployments; not durable across restarts.

Integer counters get their own HopscotchMap<String, Arc<AtomicI64>> so increment_i64 can CAS atomically without RMW-racing through the byte-keyed bucket. Readers of the byte store see the counter value as decimal ASCII on get(key) after an increment - this mirrors the JS polyfill’s setJSON/getJSON contract.

Implementations

impl InMemoryStateStore

pub fn new() -> Self

pub fn shared() -> SharedStateStore

Trait Implementations

impl Default for InMemoryStateStore

fn default() -> InMemoryStateStore

Returns the “default value” for a type.

impl StateStore for InMemoryStateStore

fn get(&self, key: &str) -> Option<Vec<u8>>

fn set(&self, key: &str, value: Vec<u8>)

fn delete(&self, key: &str)

fn increment_i64(&self, key: &str, delta: i64) -> i64

Atomically add delta to the signed integer stored under key (or 0 if absent) and return the new value. Implementations must ensure no reader sees a partial update under concurrent access.

fn list_keys(&self, _prefix: &str) -> Vec<String>

Best-effort prefix listing. The default in-memory backend returns an empty vec - embedders that need iteration should plug in a backend whose storage supports it.
