Types ¶
type BucketedPool ¶
type BucketedPool[T ~[]E, E any] struct { // contains filtered or unexported fields }
BucketedPool is a bucketed pool for variably sized slices. It is similar to prometheus/prometheus' pool.Pool, but uses zeropool.Pool internally, and generics to avoid reflection.
func NewBucketedPool ¶
func NewBucketedPool[T ~[]E, E any](minSize, maxSize int, factor int, makeFunc func(int) T) *BucketedPool[T, E]
NewBucketedPool returns a new BucketedPool with size buckets for minSize to maxSize increasing by the given factor.
func (*BucketedPool[T, E]) Get ¶
func (p *BucketedPool[T, E]) Get(size int) T
Get returns a new slice with capacity greater than or equal to size.
func (*BucketedPool[T, E]) Put ¶
func (p *BucketedPool[T, E]) Put(s T)
Put adds a slice to the right bucket in the pool. If the slice does not belong to any bucket in the pool, it is ignored.
type FastReleasingSlabPool ¶
type FastReleasingSlabPool[T any] struct { // contains filtered or unexported fields }
FastReleasingSlabPool is similar to SlabPool, but allows for fast release of slabs if they are not used anymore.
func NewFastReleasingSlabPool ¶
func NewFastReleasingSlabPool[T any](delegate Interface, slabSize int) *FastReleasingSlabPool[T]
NewFastReleasingSlabPool returns a new "fast-releasing" slab pool.
func (*FastReleasingSlabPool[T]) Get ¶
func (b *FastReleasingSlabPool[T]) Get(size int) ([]T, int)
Get returns a slice of T with the given length and capacity (both match), and slab ID that needs be used in Release call.
func (*FastReleasingSlabPool[T]) Release ¶
func (b *FastReleasingSlabPool[T]) Release(slabID int)
Release decreases reference counter for given slab ID. (Slab ids equal to or less than 0 are ignored). If reference counter is 0, slab may be returned to the delegate pool.
type Interface ¶
type Interface interface {
// Put is sync.Pool.Put().
Put(x any)
// Get is sync.Pool.Get().
Get() any
}
Interface defines the same functions of sync.Pool.
type SafeSlabPool ¶
type SafeSlabPool[T any] struct { // contains filtered or unexported fields }
SafeSlabPool wraps SlabPool to make it safe for concurrent use from multiple goroutines
func NewSafeSlabPool ¶
func NewSafeSlabPool[T any](delegate Interface, slabSize int) *SafeSlabPool[T]
func (*SafeSlabPool[T]) Get ¶
func (b *SafeSlabPool[T]) Get(size int) []T
func (*SafeSlabPool[T]) Release ¶
func (b *SafeSlabPool[T]) Release()
type SafeSlabPoolAllocator ¶
type SafeSlabPoolAllocator struct {
// contains filtered or unexported fields
}
func NewSafeSlabPoolAllocator ¶
func NewSafeSlabPoolAllocator(pool *SafeSlabPool[byte]) *SafeSlabPoolAllocator
NewSafeSlabPoolAllocator wraps the input SafeSlabPool[byte] into an allocator suitable to be used with a cache client. This function returns nil if the input SafeSlabPool[byte] is nil.
func (*SafeSlabPoolAllocator) Get ¶
func (a *SafeSlabPoolAllocator) Get(sz int) *[]byte
func (*SafeSlabPoolAllocator) Put ¶
func (a *SafeSlabPoolAllocator) Put(_ *[]byte)
type SlabPool ¶
type SlabPool[T any] struct { // contains filtered or unexported fields }
SlabPool wraps Interface and adds support to get a sub-slice of the data type T from the pool, trying to fit the slices picked from the pool as much as possible.
The slices returned by SlabPool.Get() will be released back to the pool once SlabPool.Release() is called.
SlabPool is NOT concurrency safe.
type TrackedPool ¶
func (*TrackedPool) Get ¶
func (p *TrackedPool) Get() any
func (*TrackedPool) Put ¶
func (p *TrackedPool) Put(x any)
func (*TrackedPool) Reset ¶
func (p *TrackedPool) Reset()
