Ruby | String byteslice Method

Last Updated : 07 Jan, 2020

byteslice is a String class method in Ruby which is used for the byte reference.

Syntax: str.byteslice Parameters: Here, str is the specified string. Returns:

A substring of one byte at that position if only a single integer passed.

A substring starting at the offset given by the first, and a length is given by the second if the two integers passed.

A substring containing bytes at offsets given by the range if the range is passed.

nil if the length is negative or initial offset falls outside the string or the beginning of the range is greater than the end.

Note: If an offset is negative then it is counted from the end of the string. Example 1:

Ruby

# Ruby program to demonstrate
# the byteslice method
   
# Taking a string and
# using the method
puts "Ruby String".byteslice(9)
puts "Methods".byteslice(2, 4)

Output:

n
thod

Example 2:

Ruby

# Ruby program to demonstrate
# the byteslice method
   
# Taking a string and
# using the method
puts "Ruby String".byteslice(-1)
puts "Methods".byteslice(1..4)

Output:

g
etho
