Functions ¶
func NewLoopQueue ¶
func Put ¶ added in v1.0.32
func Put(b *ByteBuffer)
Put returns byte buffer to the pool.
ByteBuffer.B mustn't be touched after returning it to the pool. Otherwise, data races will occur.
Types ¶
type ByteBuffer ¶ added in v1.0.32
type ByteBuffer struct {
// B is a byte buffer to use in append-like workloads.
// See example code for details.
B []byte
}
ByteBuffer provides byte buffer, which can be used for minimizing memory allocations.
ByteBuffer may be used with functions appending data to the given []byte slice. See example code for details.
Use Get for obtaining an empty byte buffer.
Example ¶
bb := Get()
bb.WriteString("first line\n")
bb.Write([]byte("second line\n"))
bb.B = append(bb.B, "third line\n"...)
fmt.Printf("bytebuffer contents=%q", bb.B)
// It is safe to release byte buffer now, since it is
// no longer used.
Put(bb)
func Get ¶ added in v1.0.32
func Get() *ByteBuffer
Get returns an empty byte buffer from the pool.
Got byte buffer may be returned to the pool via Put call. This reduces the number of memory allocations required for byte buffer management.
func (*ByteBuffer) Bytes ¶ added in v1.0.32
func (b *ByteBuffer) Bytes() []byte
Bytes returns b.B, i.e. all the bytes accumulated in the buffer.
The purpose of this function is bytes.Buffer compatibility.
func (*ByteBuffer) Len ¶ added in v1.0.32
func (b *ByteBuffer) Len() int
Len returns the size of the byte buffer.
func (*ByteBuffer) ReadFrom ¶ added in v1.0.32
func (b *ByteBuffer) ReadFrom(r io.Reader) (int64, error)
ReadFrom implements io.ReaderFrom.
The function appends all the data read from r to b.
func (*ByteBuffer) Reset ¶ added in v1.0.32
func (b *ByteBuffer) Reset()
Reset makes ByteBuffer.B empty.
func (*ByteBuffer) Set ¶ added in v1.0.32
func (b *ByteBuffer) Set(p []byte)
Set sets ByteBuffer.B to p.
func (*ByteBuffer) SetString ¶ added in v1.0.32
func (b *ByteBuffer) SetString(s string)
SetString sets ByteBuffer.B to s.
func (*ByteBuffer) String ¶ added in v1.0.32
func (b *ByteBuffer) String() string
String returns string representation of ByteBuffer.B.
func (*ByteBuffer) Write ¶ added in v1.0.32
func (b *ByteBuffer) Write(p []byte) (int, error)
Write implements io.Writer - it appends p to ByteBuffer.B
func (*ByteBuffer) WriteByte ¶ added in v1.0.32
func (b *ByteBuffer) WriteByte(c byte) error
WriteByte appends the byte c to the buffer.
The purpose of this function is bytes.Buffer compatibility.
The function always returns nil.
func (*ByteBuffer) WriteString ¶ added in v1.0.32
func (b *ByteBuffer) WriteString(s string) (int, error)
WriteString appends s to ByteBuffer.B.
type Pool ¶ added in v1.0.32
type Pool struct {
DefaultSize uint64
// contains filtered or unexported fields
}
Pool represents byte buffer pool.
Distinct pools may be used for distinct types of byte buffers. Properly determined byte buffer types with their own pools may help reducing memory waste.
func (*Pool) Get ¶ added in v1.0.32
func (p *Pool) Get() *ByteBuffer
Get returns new byte buffer with zero length.
The byte buffer may be returned to the pool via Put after the use in order to minimize GC overhead.
func (*Pool) Put ¶ added in v1.0.32
func (p *Pool) Put(b *ByteBuffer)
Put releases byte buffer obtained via Get to the pool.
The buffer mustn't be accessed after returning to the pool.
