+/// @brief: The type signature for a CAN signal encoder.
+///
+/// A SignalEncoder transforms a number, string or boolean into a raw floating
+/// point value that fits in the CAN signal.
+///
+/// @param[in] signal - The CAN signal to encode.
+/// @param[in] value - The dynamic field to encode.
+/// @param[out] send - An output parameter. If the encoding failed or the CAN signal should
+/// not be encoded for some other reason, this will be flipped to false.
