You're seeing just the function
brot
, go back to Pfx module for more information.
Specs
Rotates the bits of pfx
by n
positions.
Positive n
rotates right, negative rotates left. The length of the
resulting bits stays the same.
Examples
iex> brot("1.2.3.4", 8)
"4.1.2.3"
iex> brot("1.2.3.4", -8)
"2.3.4.1"
iex> brot({1, 2, 3, 4}, 8)
{4, 1, 2, 3}
iex> brot({{1, 2, 3, 4}, 32}, -8)
{{2, 3, 4, 1}, 32}
# note: the `bits` <<1, 2>> get rotated (!)
iex> brot("1.2.0.0/16", 8)
"2.1.0.0/16"
iex> brot(%Pfx{bits: <<1, 2, 3, 4>>, maxlen: 32}, 8)
%Pfx{bits: <<4, 1, 2, 3>>, maxlen: 32}
