Types

type Buffer

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

Buffer is a thread safe version of bytes.Buffer.

func NewBuffer

func NewBuffer(b []byte) *Buffer

func (*Buffer) Bytes

func (sb *Buffer) Bytes() []byte

func (*Buffer) Len

func (sb *Buffer) Len() int

func (*Buffer) Next

func (sb *Buffer) Next(n int) []byte

func (*Buffer) Read

func (sb *Buffer) Read(p []byte) (int, error)

func (*Buffer) ReadByte

func (sb *Buffer) ReadByte() (byte, error)

func (*Buffer) ReadBytes

func (sb *Buffer) ReadBytes(delim byte) ([]byte, error)

func (*Buffer) ReadFrom

func (sb *Buffer) ReadFrom(r io.Reader) (int64, error)

func (*Buffer) ReadRune

func (sb *Buffer) ReadRune() (rune, int, error)

func (*Buffer) ReadString

func (sb *Buffer) ReadString(delim byte) (string, error)

func (*Buffer) Reset

func (sb *Buffer) Reset()

func (*Buffer) String

func (sb *Buffer) String() string

func (*Buffer) Truncate

func (sb *Buffer) Truncate(n int)

func (*Buffer) UnreadByte

func (sb *Buffer) UnreadByte() error

func (*Buffer) UnreadRune

func (sb *Buffer) UnreadRune() error

func (*Buffer) Write

func (sb *Buffer) Write(p []byte) (int, error)

func (*Buffer) WriteByte

func (sb *Buffer) WriteByte(c byte) error

func (*Buffer) WriteRune

func (sb *Buffer) WriteRune(r rune) (int, error)

func (*Buffer) WriteString

func (sb *Buffer) WriteString(s string) (int, error)

func (*Buffer) WriteTo

func (sb *Buffer) WriteTo(w io.Writer) (int64, error)

type BytesReader

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

BytesReader is a thread safe version of bytes.Reader.

func NewBytesReader

func NewBytesReader(b []byte) *BytesReader

func (*BytesReader) Len

func (r *BytesReader) Len() int

func (*BytesReader) Read

func (r *BytesReader) Read(b []byte) (int, error)

func (*BytesReader) ReadAt

func (r *BytesReader) ReadAt(b []byte, off int64) (int, error)

func (*BytesReader) ReadByte

func (r *BytesReader) ReadByte() (byte, error)

func (*BytesReader) ReadRune

func (r *BytesReader) ReadRune() (rune, int, error)

func (*BytesReader) Seek

func (r *BytesReader) Seek(offset int64, whence int) (int64, error)

func (*BytesReader) UnreadByte

func (r *BytesReader) UnreadByte() error

func (*BytesReader) UnreadRune

func (r *BytesReader) UnreadRune() error

func (*BytesReader) WriteTo

func (r *BytesReader) WriteTo(w io.Writer) (int64, error)

type Counter

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

Counter implements a thread-safe, lock-free counter, that supports operations like increment and decrement.

It uses an int64 internally, so all int64 boundaries also apply here.

func NewCounter

func NewCounter(initial int64) *Counter

NewCounter creates a new counter with the given value as the initial value.

func (*Counter) Decrement

func (c *Counter) Decrement()

Decrement decrements the value of c by 1.

func (*Counter) Increment

func (c *Counter) Increment()

Increment increments the value of c by 1.

func (*Counter) Val

func (c *Counter) Val() int64

Val returns the current value of the counter.
