cfunction
(buffer/slice bytes &opt start end)
Takes a slice of a byte sequence from start to end. The range is
half open, [start, end). Indexes can also be negative, indicating
indexing from the end of the end of the array. By default, start is
0 and end is the length of the buffer. Returns a new buffer.
Example usage
janet:1:> (def buf @"ABCDE")

janet:4:> (buffer/slice buf 0 1)
