Types

type Cache

type Cache struct {
	// contains filtered or unexported fields
}

Cache deduplicates outgoing messages within a TTL window. Reserve returns true if the (dst, msg) pair is new; false if it was seen within the TTL.

func New

func New(ttl time.Duration) *Cache

New creates a Cache with the given TTL. TTL == 0 disables dedup (Reserve always returns true).

func (*Cache) Reserve

func (c *Cache) Reserve(dst, msg string) bool
