Event field type for keyboard modifier state.

Parses a wire-format modifier map (string keys, boolean values) into a %Plushie.KeyModifiers{} struct. Missing fields default to false.

Examples

iex> Plushie.Type.KeyModifiers.parse(%{"ctrl" => true, "shift" => false})
{:ok, %Plushie.KeyModifiers{ctrl: true, shift: false, alt: false, logo: false, command: false}}

iex> Plushie.Type.KeyModifiers.parse(%{})
{:ok, %Plushie.KeyModifiers{}}

iex> Plushie.Type.KeyModifiers.parse(nil)
{:ok, %Plushie.KeyModifiers{}}
