Struct InMemoryBackend 

pub struct InMemoryBackend { /* private fields */ }

In-memory backend (simulates Redis)

Uses RwLock<HashMap> to store counters, simulating Redis’s INCR + EXPIRE behavior. Suitable for single-machine scenarios and testing; not suitable for real distributed environments.

Implementations

impl InMemoryBackend

pub fn new() -> Self

Trait Implementations

impl Default for InMemoryBackend

fn default() -> Self

Returns the “default value” for a type.

impl DistributedBackend for InMemoryBackend

fn incr_and_get( &self, key: &str, window_secs: u64, window_start: i64, _max_requests: u64, ) -> Result<(u64, i64), RateLimitError>

Atomically increments and returns the value after increment

fn get(&self, key: &str) -> Result<Option<(u64, i64)>, RateLimitError>

Returns the current count (without incrementing)

fn reset_key(&self, key: &str) -> Result<(), RateLimitError>

Resets the key (deletes it)
