Checks if the given pid is a Combo.Channel process.

Returns a list of all currently connected channels for the given Combo.Socket pid.

Each channel is represented as a map with the following keys:

• :pid - the pid of the channel process
• :status - the status of the channel
• :topic - the topic of the channel

Examples

iex> pid = Combo.Debug.list_sockets() |> Enum.at(0) |> Map.fetch!(:pid)
iex> Combo.Debug.list_channels(pid)
{:ok,
 [
   %{pid: #PID<0.1702.0>, status: :joined, topic: "t1"},
   %{pid: #PID<0.1727.0>, status: :joined, topic: "t2"}
 ]}

iex> Combo.Debug.list_channels(pid(0,456,0))
{:error, :not_alive}

Returns a list of all currently connected Combo.Socket transport processes.

Note that custom sockets implementing the Combo.Socket.Transport behaviour are not listed.

Each process corresponds to one connection that can have multiple channels. See Combo.Debug.list_channels/1.

Examples

iex> Combo.Debug.list_sockets()
[%{pid: #PID<0.123.0>, module: Combo.Socket, id: nil}]

Returns the socket of the channel process.

Note: this only works for channels defined with use Combo.Channel.

Examples

iex> pid = Combo.Debug.list_sockets() |> Enum.at(0) |> Map.fetch!(:pid)
iex> {:ok, channels} = Combo.Debug.list_channels(pid)
iex> channels |> Enum.at(0) |> Map.fetch!(:pid) |> socket()
{:ok, %Combo.Socket{...}}

iex> socket(pid(0,456,0))
{:error, :not_alive_or_not_a_channel}

Returns true if the given pid is a Combo.Socket transport process.

It returns false for custom sockets implementing the Combo.Socket.Transport behaviour.

Examples

iex> Combo.Debug.list_sockets() |> Enum.at(0) |> Map.fetch!(:pid) |> socket_process?()
true

iex> socket_process?(pid(0,456,0))
false
