Detailed Description

template<class Lhs_T, class Rhs_T>
struct micro_os_plus::micro_test_plus::detail::lt_< Lhs_T, Rhs_T >

Template Parameters

Lhs_T	The type of the left-hand operand.
Rhs_T	The type of the right-hand operand.

The lt_ struct template provides a type-safe mechanism for evaluating whether the left-hand operand is less than the right-hand operand within the framework.

This comparator supports a variety of operand types, including those with static values and generic types. For types with static values, the comparison is performed directly. For all other types, the generic getter is used to retrieve and compare the values.

The implementation is optimised for use in embedded environments and supports both compile-time and run-time evaluation.

All definitions are intended for internal use within the framework and are implemented in the include/micro-os-plus folder to maintain a structured and modular codebase.

template<class Lhs_T, class Rhs_T>

micro_os_plus::micro_test_plus::detail::lt_< Lhs_T, Rhs_T >::lt_ ( const Lhs_T & lhs = {}, const Rhs_T & rhs = {} )

inlineconstexpr

Parameters

lhs	The left-hand operand.
rhs	The right-hand operand.

Evaluates whether the left-hand operand is less than the right-hand operand at construction, supporting static values and generic types. The result is stored in the value_ member for efficient access.
