Struct CacheRateLimiter 

pub struct CacheRateLimiter { /* private fields */ }

Rate-limit counters kept in a Cache.

Implementations

impl CacheRateLimiter

pub fn new(cache: Arc<dyn Cache>) -> Self

Count in cache, under the rate: prefix.

pub fn with_prefix(self, prefix: impl Into<String>) -> Self

Count under a different prefix.

Worth changing when the cache is shared with something else that might pick the same names.

pub fn cache(&self) -> &Arc<dyn Cache>

The cache underneath.

impl RateLimitStore for CacheRateLimiter

fn hit<'a>( &'a self, key: &'a str, window: Duration, ) -> BoxFuture<'a, Result<Hit>>

Record one hit against key, in a window of window.

fn peek<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Result<Option<Hit>>>

The state of key without recording anything.

fn clear<'a>(&'a self, key: &'a str) -> BoxFuture<'a, Result<()>>

Forget key, restoring its full allowance.

fn is_shared(&self) -> bool

Whether other instances of this application see the same counters.

fn name(&self) -> &str
