decode(binary(), encoding()) :: {:ok, binary()} | {:error, term()}

Decodes the given binary data using the specified BSV.Util.encoding/0.

Returns the result in an :ok / :error tuple pair.

Examples

iex> BSV.Util.decode("aGVsbG8gd29ybGQ=", :base64)
{:ok, "hello world"}

iex> BSV.Util.decode("68656c6c6f20776f726c64", :hex)
{:ok, "hello world"}

Specs

decode!(binary(), encoding()) :: binary()
