Struct MemoryBackend 

pub struct MemoryBackend { /* private fields */ }

Process-lifetime, in-memory backend. The default until a durable store is configured.

Trait Implementations

impl Default for MemoryBackend

fn default() -> MemoryBackend

Returns the “default value” for a type.

impl KvBackend for MemoryBackend

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

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

fn delete(&self, key: &[u8])

fn increment(&self, key: &[u8], delta: i64) -> i64

Atomic add-and-get. An unset counter starts at 0; delta is signed.

fn try_acquire( &self, key: &[u8], cost: u64, spec: Bucket, now_ms: u64, ) -> Acquire

Atomic token-bucket acquire against the now_ms request-clock snapshot. The refill + counting stay host-native (ADR 000005) — they never cross the WASM boundary; the filter only decided to consult the limiter.
