Pfx.padl

You're seeing just the function padl, go back to Pfx module for more information.

padl(pfx)

Specs

padl(prefix()) :: prefix()

Pads the bits in pfx on the left to its full length using 0-bits.

Examples

iex> padl("1.2.0.0/16")
"0.0.1.2"

iex> padl({{1, 2, 0, 0}, 16})
{{0, 0, 1, 2}, 32}

iex> padl(%Pfx{bits: <<1, 2>>, maxlen: 32})
%Pfx{bits: <<0, 0, 1, 2>>, maxlen: 32}

padl(pfx, bit)

Specs

padl(prefix(), 0 | 1) :: prefix()

Left pad the pfx.bits to its full length using either 0 or 1-bits.

Examples

iex> padl("1.2.0.0/16", 1)
"255.255.1.2"

iex> padl({{1, 2, 0, 0}, 16}, 1)
{{255, 255, 1, 2}, 32}

iex> padl(%Pfx{bits: <<1, 2>>, maxlen: 32}, 1)
%Pfx{bits: <<255, 255, 1, 2>>, maxlen: 32}

padl(pfx, bit, n)

Specs

padl(prefix(), 0 | 1, non_neg_integer()) :: prefix()

Pads the bits in pfx on the Left with n bits of either 0 or 1's.

Examples

iex> padl("255.255.0.0/16", 0, 16)
"0.0.255.255"

iex> padl("255.255.0.0/16", 1, 16)
"255.255.255.255"

iex> padl({{255, 255, 0, 0}, 16}, 0, 16)
{{0, 0, 255, 255}, 32}

iex> padl(%Pfx{bits: <<255, 255>>, maxlen: 32}, 0, 16)
%Pfx{bits: <<0, 0, 255, 255>>, maxlen: 32}
