Types

type Cache

type Cache interface {
	// Put stores the given (key,value) pair, replacing existing value if key already exists.
	Put(key interface{}, value Value) error
	// Get returns the value for a given key.
	Get(key interface{}) (Value, error)
	// Len returns number of elements in the cache.
	Len() int
}

Cache represents a generic cache.

type CacheableBlock

type CacheableBlock struct {
	*util.Block
}

CacheableBlock is a wrapper around the util.Block type which provides a Size method used by the cache to target certain memory usage.

func (*CacheableBlock) Size

func (c *CacheableBlock) Size() (uint64, error)

Size returns size of this block in bytes.

type CacheableFilter

type CacheableFilter struct {
	*gcs.Filter
}

CacheableFilter is a wrapper around Filter type which provides a Size method used by the cache to target certain memory usage.

func (*CacheableFilter) Size

func (c *CacheableFilter) Size() (uint64, error)

Size returns size of this filter in bytes.

type Value

type Value interface {
	// Size determines how big this entry would be in the cache. For example, for a filter, it could be the size of the
	// filter in bytes.
	Size() (uint64, error)
}

Value represents a value stored in the Cache.
