Yet Another Queue module for Elixir

Yaq implements a double-ended queue in Elixir without using the Erlang :queue module. While very nice, :queue has a few limitations that I needed to work past:

• Some of the commands in :queue return a badarg instead of best-effort values. For example, calling :queue(n, q) when n is larger than the size of q raises an ArgumentError instead of giving me some value less than n. This may be fine in many circumstances, but my use cases just ask for some value in return.
• Getting the size of :queue is an O(N) operation, when it should be O(1)
• I wanted a module that I could use with other common Elixir libraries, such as Enum
• :queue is not very pipeable. The |> operator is very convenient and one of the killer features of Elixir

Yaq implements the Enum and Collectable protocols

• Double-ended quque
• Implements Enumerable, Collectable protocols

The package can be installed by adding yaq to your list of dependencies in mix.exs:

def deps do
  [
    {:yaq, "~> 1.1"}
  ]
end
