Types

type Arena

type Arena[T any] struct {
	// contains filtered or unexported fields
}

Arena is a generic arena allocator that pre-allocates a slice and provides goroutine-safe allocation of individual items or batches

func New

func New[T any](capacity uint64) *Arena[T]

New creates a new arena with the specified capacity

func (*Arena[T]) Alloc

func (a *Arena[T]) Alloc() (*T, bool)

Alloc allocates a single item from the arena. Returns a pointer to the item and true if allocated from arena, or a pointer to a heap-allocated item and false if arena is full.

func (*Arena[T]) AllocN

func (a *Arena[T]) AllocN(n uint64) ([]T, bool)

AllocN allocates n items from the arena. Returns a slice of the items and true if all allocated from arena, or a heap-allocated slice and false if arena doesn't have enough space.

func (*Arena[T]) Reset

func (a *Arena[T]) Reset()
