Variables

❖
var ErrSizeLimit error = err{}

type Dynamic Uses

❖
type Dynamic struct {
    // contains filtered or unexported fields
}

Dynamic is a variable-capacity buffer. The default value is a valid buffer.

func MakeDynamic Uses

❖
func MakeDynamic(b []byte) Dynamic

MakeDynamic buffer.

This function can be used in field initializer expressions. The initialized field must not be copied.

func MakeDynamicHint Uses

❖
func MakeDynamicHint(b []byte, maxSizeHint int) Dynamic

MakeDynamicHint avoids making excessive allocations if the maximum buffer size can be estimated in advance. The slice must be empty.

This function can be used in field initializer expressions. The initialized field must not be copied.

func NewDynamic Uses

❖
func NewDynamic(b []byte) *Dynamic

NewDynamic buffer.

func NewDynamicHint Uses

❖
func NewDynamicHint(b []byte, maxSizeHint int) *Dynamic

NewDynamicHint avoids making excessive allocations if the maximum buffer size can be estimated in advance. The slice must be empty.

func (*Dynamic) Bytes Uses

❖
func (d *Dynamic) Bytes() []byte

Bytes doesn't panic.

func (*Dynamic) Extend Uses

❖
func (d *Dynamic) Extend(addLen int) []byte

Extend doesn't panic unless out of memory.

func (*Dynamic) Len Uses

❖
func (d *Dynamic) Len() int

Len doesn't panic.

func (*Dynamic) PutByte Uses

❖
func (d *Dynamic) PutByte(value byte)

PutBytes doesn't panic unless out of memory.

func (*Dynamic) PutUint32 Uses

❖
func (d *Dynamic) PutUint32(i uint32)

Extend doesn't panic unless out of memory.

func (*Dynamic) ResizeBytes Uses

❖
func (d *Dynamic) ResizeBytes(newLen int) []byte

ResizeBytes doesn't panic unless out of memory.

type Limited Uses

❖
type Limited struct {
    // contains filtered or unexported fields
}

Limited is a dynamic buffer with a maximum size. The default value is an empty buffer that cannot grow.

func MakeLimited Uses

❖
func MakeLimited(b []byte, maxSize int) Limited

MakeLimited buffer with a maximum size. The slice must be empty.

This function can be used in field initializer expressions. The initialized field must not be copied.

func NewLimited Uses

❖
func NewLimited(b []byte, maxSize int) *Limited

NewLimited buffer with a maximum size. The slice must be empty.

func (*Limited) Bytes Uses

❖
func (l *Limited) Bytes() []byte

Bytes doesn't panic.

func (*Limited) Extend Uses

❖
func (l *Limited) Extend(n int) []byte

Extend panicks with ErrSizeLimit if n bytes cannot be appended to the buffer.

func (*Limited) Len Uses

❖
func (l *Limited) Len() int

Len doesn't panic.

func (*Limited) PutByte Uses

❖
func (l *Limited) PutByte(value byte)

PutByte panicks with ErrSizeLimit if the buffer is already full.

func (*Limited) PutUint32 Uses

❖
func (l *Limited) PutUint32(i uint32)

Extend panicks with ErrSizeLimit if 4 bytes cannot be appended to the buffer.

func (*Limited) ResizeBytes Uses

❖
func (l *Limited) ResizeBytes(n int) []byte

ResizeBytes panicks with ErrSizeLimit if n is larger than maximum buffer size.

type Static Uses

❖
type Static struct {
    // contains filtered or unexported fields
}

Static is a fixed-capacity buffer, for wrapping a memory-mapped region. The default value is a zero-capacity buffer.

func MakeStatic Uses

❖
func MakeStatic(b []byte) Static

MakeStatic buffer.

This function can be used in field initializer expressions. The initialized field must not be copied.

func NewStatic Uses

❖
func NewStatic(b []byte) *Static

NewStatic buffer.

func (*Static) Bytes Uses

❖
func (s *Static) Bytes() []byte

Bytes doesn't panic.

func (*Static) Cap Uses

❖
func (s *Static) Cap() int

Capacity of the static buffer.

func (*Static) Extend Uses

❖
func (s *Static) Extend(n int) []byte

Extend panicks with ErrSizeLimit if n bytes cannot be appended to the buffer.

func (*Static) Len Uses

❖
func (s *Static) Len() int

Len doesn't panic.

func (*Static) PutByte Uses

❖
func (s *Static) PutByte(value byte)

PutByte panicks with ErrSizeLimit if the buffer is already full.

func (*Static) PutUint32 Uses

❖
func (s *Static) PutUint32(i uint32)

Extend panicks with ErrSizeLimit if 4 bytes cannot be appended to the buffer.

func (*Static) ResizeBytes Uses

❖
func (s *Static) ResizeBytes(n int) []byte

ResizeBytes panicks with ErrSizeLimit if n is larger than buffer capacity.

func (*Static) Write Uses

❖
func (s *Static) Write(b []byte) (n int, err error)

Write doesn't panic.
