Summary
Functions
Converts a bit into a boolean.
Converts a boolean into a bit.
Decodes a 128-bit binary into an IPv6 address tuple.
Encodes an IPv6 address tuple into a 128-bit binary.
Functions
@spec bit_to_bool(0 | 1) :: boolean()
Converts a bit into a boolean.
Examples
iex> bit_to_bool(1)
true
iex> bit_to_bool(0)
false
@spec bool_to_bit(boolean()) :: 0 | 1
Converts a boolean into a bit.
Examples
iex> bool_to_bit(true)
1
iex> bool_to_bit(false)
0
@spec decode_ipv6_address(binary()) :: :inet.ip6_address()
Decodes a 128-bit binary into an IPv6 address tuple.
Examples
iex> decode_ipv6_address(<<0xfd00::16, 0xaaaa::16, 0::16, 0::16, 0::16, 0::16, 0::16, 2::16>>)
{0xfd00, 0xaaaa, 0, 0, 0, 0, 0, 2}
@spec encode_ipv6_address(:inet.ip6_address()) :: binary()
Encodes an IPv6 address tuple into a 128-bit binary.
Examples
iex> encode_ipv6_address({0xfd00, 0xaaaa, 0, 0, 0, 0, 0, 2})
<<0xfd00::16, 0xaaaa::16, 0::16, 0::16, 0::16, 0::16, 0::16, 2::16>>
