type ByteWriter ¶
ByteWriter is a simple wrapper over a byte slice that supports writing anywhere
type ByteWriter struct {
// contains filtered or unexported fields
}
func NewByteWriter ¶
func NewByteWriter(n int) *ByteWriter
NewByteWriter creates a new ByteWriter of the specified size
func NewByteWriterSlice ¶
func NewByteWriterSlice(buffer []byte) *ByteWriter
NewByteWriterSlice creates a new ByteWriter using the passed slice
func (*ByteWriter) Bytes ¶
