Struct MemoryBackend 

pub struct MemoryBackend { /* private fields */ }

In-memory storage backend suitable for single-node deployments.

Implementations

impl MemoryBackend

pub fn new() -> Self

Creates a backend with the default namespace.

pub fn with_namespace(namespace: impl Into<Arc<str>>) -> Self

Creates a backend with a custom namespace.

impl MemoryBackend

pub fn storage_key<P>(namespace: &str, subject: &str, quota: Quota) -> String

where P: RateLimitPolicy,

Builds a storage key for the given subject and quota.

Trait Implementations

impl Clone for MemoryBackend

fn clone(&self) -> MemoryBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for MemoryBackend

fn default() -> Self

Returns the “default value” for a type.

impl RateLimitBackend for MemoryBackend

type Error = CodecError

Error type returned by this backend.

fn namespace(&self) -> &str

Namespace used to isolate keys for this backend instance.

fn transact<'life0, 'life1, 'async_trait, P>( &'life0 self, storage_key: &'life1 str, quota: Quota, now_ms: u64, ) -> Pin<Box<dyn Future<Output = Result<RateLimitSnapshot, Self::Error>> + Send + 'async_trait>>

where P: RateLimitPolicy + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Atomically loads policy state, applies the rate limit algorithm, and persists the result.
