Types

type Pool

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

Pool contains logic of reusing byte slices of various size.

func New

func New(min, max int) *Pool

New creates new Pool that reuses slices which size is in logarithmic range [min, max].

Note that it is a shortcut for Custom() constructor with Options provided by pool.WithLogSizeMapping() and pool.WithLogSizeRange(min, max) calls.

func (*Pool) Get

func (p *Pool) Get(c int) *bytes.Buffer

Get returns probably reused slice of bytes with at least capacity of c and exactly len of n.

func (*Pool) Put

func (p *Pool) Put(bf *bytes.Buffer)

Put returns given slice to reuse pool. It does not reuse bytes whose size is not power of two or is out of pool min/max range.
