XDR.Bool - Boolean

Boolean is an Enumeration implementation that allows us to create boolean types. An XDR Boolean type is an Enumeration with the keyword list [false: 0, true: 1] as declarations.

Boolean - RFC 4506

Usage

Encoding

iex(1)> XDR.Bool.new(true) |> XDR.Bool.encode_xdr()
{:ok, <<0, 0, 0, 0>>}

iex(1)> XDR.Bool.new(true) |> XDR.Bool.encode_xdr!()
<<0, 0, 0, 0>>

Decoding

iex(1)> XDR.Bool.decode_xdr(<<0, 0, 0, 1>>)
{:ok, {%XDR.Bool{declarations: [false: 0, true: 1], identifier: true}, ""}}

iex(1)> XDR.Bool.decode_xdr!(<<0, 0, 0, 1>>)
{%XDR.Bool{declarations: [false: 0, true: 1], identifier: true}, ""}

Custom Boolean example

  defmodule CustomBoolean do

    @type t :: XDR.Bool.t()

    defdelegate new(bool_value), to: XDR.Bool
    defdelegate encode_xdr(bool), to: XDR.Bool
    defdelegate encode_xdr!(bool), to: XDR.Bool
    defdelegate decode_xdr(bytes), to: XDR.Bool
    defdelegate decode_xdr!(bytes), to: XDR.Bool
  end

# Encode
CustomBoolean.new(true) |> CustomBoolean.encode_xdr()

# Decode
CustomBoolean.decode_xdr(<<0, 0, 0, 1>>)
