Bytes provides a slice of the bytes written. This slice should not be written to.

Write writes up to len(buf) bytes to the internal ring, overriding older data if necessary.

NewBuffer creates a new buffer of a given size. The size must be greater than 0.

Reset resets the buffer so it has no content.

TotalWritten provides the total number of bytes written

Size returns the size of the buffer

String returns the contents of the buffer as a string
