}

Functions

decode(data)

@spec decode(binary()) :: {:ok, t()} | :error

Decodes a complete Art-Net binary as this packet type.

encode(packet)

@spec encode(t()) :: {:ok, binary()} | :error

Encodes this packet struct into a complete Art-Net binary.

new(attrs)

@spec new(map() | Keyword.t()) :: {:ok, t()} | {:error, ArtNet.EncodeError.t()}

Builds a validated packet struct from a map or keyword list.

new!(attrs)

@spec new!(map() | Keyword.t()) :: t()

Builds a validated packet struct from a map or keyword list.

Raises ArtNet.EncodeError when validation fails.

op_code()

@spec op_code() :: pos_integer()

Returns the Art-Net OpCode value for this packet module.

The OpCode is 0x2800.

require_version_header?()

@spec require_version_header?() :: boolean()
