Struct InMemoryStateStore 

pub struct InMemoryStateStore { /* private fields */ }

In-memory state store using DashMap

Warning: Only suitable for single-instance deployments! For distributed systems, use RedisStateStore instead.

SECURITY

• Bounded to MAX_STATES entries to prevent unbounded memory growth
• Expired states are automatically cleaned up on store operations
• Implements LRU-like eviction when max capacity is reached

Implementations

impl InMemoryStateStore

pub fn new() -> Self

Create a new in-memory state store with default limits

pub fn with_max_states(max_states: usize) -> Self

Create a new in-memory state store with custom max size

Arguments

• max_states - Maximum number of states to store

Trait Implementations
