Functions ¶

func Free ¶

func Free(purpose Purpose, b []byte)

Free frees the specified slice. It has to be exactly the slice that was returned by New.

func New ¶

func New(purpose Purpose, n int) []byte

New allocates a slice of size n. The returned slice is from manually managed memory and MUST be released by calling Free. Failure to do so will result in a memory leak.

Types ¶

type Metrics ¶

type Metrics [NumPurposes]struct {
	// InUseBytes is the total number of bytes currently allocated. This is just
	// the sum of the lengths of the allocations and does not include any overhead
	// or fragmentation.
	InUseBytes uint64
}

Metrics contains memory statistics by purpose.

func GetMetrics ¶

func GetMetrics() Metrics

GetMetrics returns manual memory usage statistics.

type Purpose ¶

type Purpose uint8

Purpose identifies the use-case for an allocation.

const (
	BlockCacheMap Purpose
	BlockCacheEntry
	BlockCacheData
	MemTable

	NumPurposes
)
