bits(bitstring()) :: [0 | 1]

Returns bits for any binary data.

Example:

iex> QRCodeEx.Encode.bits(<<123, 4>>)
[0, 1, 1, 1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0]

Specs

encode(binary(), QRCodeEx.SpecTable.error_correction_level()) ::
  {QRCodeEx.SpecTable.version(), QRCodeEx.SpecTable.error_correction_level(),
   [0 | 1]}

Encode the binary.

Example:

iex> QRCodeEx.Encode.encode("hello world!", :l)
{1, :l, [0, 1, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 0, 1, 0, 0, 0, 0, 1, 1, 0, 0, 1,
 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 0, 1, 1, 0, 1, 1, 0, 0, 0, 1, 1, 0, 1, 1, 1, 1,
 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 1, 0, 1,
 1, 1, 0, 0, 1, 0, 0, 1, 1, 0, 1, 1, 0, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1, 0,
 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1, 1,
 1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1, 1, 1, 0, 1, 1, 0, 0]}

encode(binary(), QRCodeEx.SpecTable.error_correction_level(), bitstring()) ::
  {QRCodeEx.SpecTable.version(), QRCodeEx.SpecTable.error_correction_level(),
   [0 | 1]}

Specs

version(binary(), QRCodeEx.SpecTable.error_correction_level()) ::
  {:error, :no_version_found} | {:ok, QRCodeEx.SpecTable.version()}

Returns the lowest version for the given binary.

Example:

iex> QRCodeEx.Encode.version("hello world!", :l)
{:ok, 1}
