Iptrie.keys

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

keys(trie)

Specs

keys(t()) :: [prefix()]

Returns all prefixes stored in all available radix trees in trie.

The prefixes are reconstructed as Pfx.t/0 by combining the stored bitstrings with the Radix-tree's type, that is the maxlen property associated with the radix tree whose keys are being retrieved.

Example

iex> ipt = new()
...> |> put("1.1.1.0/24", 1)
...> |> put("2.2.2.0/24", 2)
...> |> put("acdc:1975::/32", 3)
...> |> put("acdc:2021::/32", 4)
iex>
iex> keys(ipt)
[
  %Pfx{bits: <<1, 1, 1>>, maxlen: 32},
  %Pfx{bits: <<2, 2, 2>>, maxlen: 32},
  %Pfx{bits: <<0xacdc::16, 0x1975::16>>, maxlen: 128},
  %Pfx{bits: <<0xacdc::16, 0x2021::16>>, maxlen: 128}
]

keys(trie, type)

Specs

keys(t(), type()) :: [prefix()]

Returns the prefixes stored in the radix tree in trie for given type.

Note that the Iptrie keys are returned as Pfx.t/0 structs.

Example

iex> ipt = new()
...> |> put("1.1.1.0/24", 1)
...> |> put("2.2.2.0/24", 2)
...> |> put("acdc:1975::/32", 3)
...> |> put("acdc:2021::/32", 4)

iex> keys(ipt, 32)
[
  %Pfx{bits: <<1, 1, 1>>, maxlen: 32},
  %Pfx{bits: <<2, 2, 2>>, maxlen: 32}
]
iex>
iex> keys(ipt, 128)
[
  %Pfx{bits: <<0xacdc::16, 0x1975::16>>, maxlen: 128},
  %Pfx{bits: <<0xacdc::16, 0x2021::16>>, maxlen: 128}
