Summarized all of Hash functions in Rails.ActiveSupport.
If a function with the same name already exists in Elixir, that is not implemented.
Defines all of here functions when use RMap.ActiveSupport.

Functions
Validates all keys in a map match given keys, raising ArgumentError on a mismatch.
Returns a list with all keys converted to strings. This includes the keys from the root map and from all nested maps and arrays.
Returns a list with all keys converted to atom. This includes the keys from the root map and from all nested maps and arrays.
Returns a map with all keys converted by the function. This includes the keys from the root map and from all nested maps and arrays.

assert_valid_keys(map, keys)
Specs
Validates all keys in a map match given keys, raising ArgumentError on a mismatch.
Examples
iex> RMap.assert_valid_keys(%{name: "Rob", years: "28"}, [:name, :age])
** (ArgumentError) Unknown key: years. Valid keys are: name, age
iex> RMap.assert_valid_keys(%{name: "Rob", age: "28"}, ["age"])
** (ArgumentError) Unknown key: age. Valid keys are: age
iex> RMap.assert_valid_keys(%{name: "Rob", age: "28"}, [:name, :age])
:okatomize_keys(map)
deep_atomize_keys(map)
deep_stringify_keys(map)
Specs
Returns a list with all keys converted to strings. This includes the keys from the root map and from all nested maps and arrays.
Examples
iex> RMap.deep_stringify_keys(%{name: "Rob", years: "28", nested: %{ a: 1 }})
%{"name" => "Rob", "nested" => %{"a" => 1}, "years" => "28"}
iex> RMap.deep_stringify_keys(%{a: %{b: %{c: 1}, d: [%{a: 1, b: %{c: 2}}]}})
%{"a" => %{"b" => %{"c" => 1}, "d" => [%{"a" => 1, "b" => %{"c" => 2}}]}}deep_symbolize_keys(map)
Specs
Returns a list with all keys converted to atom. This includes the keys from the root map and from all nested maps and arrays.
Examples
iex> RMap.deep_symbolize_keys(%{"name" => "Rob", "years" => "28", "nested" => %{ "a" => 1 }})
%{name: "Rob", nested: %{a: 1}, years: "28"}
iex> RMap.deep_symbolize_keys(%{"a" => %{"b" => %{"c" => 1}, "d" => [%{"a" => 1, "b" => %{"c" => 2}}]}})
%{a: %{b: %{c: 1}, d: [%{a: 1, b: %{c: 2}}]}}deep_transform_keys(map, func)
Specs
Returns a map with all keys converted by the function. This includes the keys from the root map and from all nested maps and arrays.
Examples
iex> RMap.deep_transform_keys(%{a: %{b: %{c: 1}}}, &to_string(&1))
%{"a" => %{"b" => %{"c" => 1}}}
iex> RMap.deep_transform_keys(%{a: %{b: %{c: 1}, d: [%{a: 1, b: %{c: 2}}]}}, &inspect(&1))
%{":a" => %{":b" => %{":c" => 1}, ":d" => [%{":a" => 1, ":b" => %{":c" => 2}}]}}deep_transform_values(map, func)
Specs
Returns a map with all values converted by the function. This includes the keys from the root map and from all nested maps and arrays.
Examples
iex> RMap.deep_transform_values(%{a: %{b: %{c: 1}}, d: 2}, &inspect(&1))
%{a: %{b: %{c: "1"}}, d: "2"}
iex> RMap.deep_transform_values(%{a: %{b: %{c: 1}, d: [%{a: 1, b: %{c: 2}}]}}, &inspect(&1))
%{a: %{b: %{c: "1"}, d: [%{a: "1", b: %{c: "2"}}]}}stringify_keys(map)
Specs
Returns a map with all keys converted to strings.
Examples
iex> RMap.stringify_keys(%{name: "Rob", years: "28", nested: %{ a: 1 }})
%{"name" => "Rob", "nested" => %{a: 1}, "years" => "28"}symbolize_keys(map)
Specs
Returns a map with all keys converted to atom.
Examples
iex> RMap.symbolize_keys(%{"name" => "Rob", "years" => "28", "nested" => %{ "a" => 1 }})
