commrat::PrimaryInputIndex< PrimaryT, InputsTuple > Struct Template Reference

Extract the index of the primary input type within Inputs<Ts...> More...

Detailed Description

template<typename PrimaryT, typename InputsTuple>
struct commrat::PrimaryInputIndex< PrimaryT, InputsTuple >

Extract the index of the primary input type within Inputs<Ts...>

Used for compile-time validation and runtime lookup of the primary input mailbox in multi-input modules.

Template Parameters

PrimaryT	The payload type designated as primary (from PrimaryInput<T>)
InputsTuple	The tuple of input types (from Inputs<Ts...>::PayloadTypes)

Example:

using Inputs = Inputs<IMUData, GPSData, LidarData>;
using Primary = PrimaryInput<GPSData>;
 
// Find GPSData index in (IMUData, GPSData, LidarData)
constexpr size_t idx = PrimaryInputIndex<GPS Data,
                                         typename Inputs::PayloadTypes>::value;
// idx == 1
