template<std::size_t SmallObjectOptimisationSize = sizeof(std::size_t)>
class arg_router::utility::unsafe_any_t< SmallObjectOptimisationSize >
Type erasure type similar to std::any but has no type checking safety features.
- Template Parameters
-
| SmallObjectOptimisationSize | Size in bytes of the small object optimisation limit. Holding objects larger will incur heap allocation. Defaults to word size |
Definition at line 21 of file unsafe_any.hpp.
template<std::size_t SmallObjectOptimisationSize = sizeof(std::size_t)>
template<typename T , typename = std::enable_if_t<use_internal_storage<T> && !std::is_same_v<std::decay_t<T>, unsafe_any_t>>>
Constructs an unsafe_any_t from value.
This constructor only takes part in overload resolution if T fits inside the internal storage.
- Template Parameters
-
- Parameters
-
| value | Value to initialise from, will move construct if an rvalue is passed in |

template<typename T , typename Allocator = config::allocator<std::decay_t<T>>, typename = std::enable_if_t<!use_internal_storage<T> && !std::is_same_v<std::decay_t<T>, unsafe_any_t>>>
Constructs an unsafe_any_t from value.
This constructor only takes part in overload resolution if T does not fit inside the internal storage.
- Template Parameters
-
| T | Type to construct from |
| Allocator | Allocator type, only used when not using internal storage |
- Parameters
-
| value | Value to initialise from, will move construct if an rvalue is passed in |
| alloc | Allocator instance |

template<std::size_t SmallObjectOptimisationSize = sizeof(std::size_t)>
template<typename T , typename DecayType = std::decay_t<T>>
Returns a reference to the held object.
Undefined behaviour if T is not the held type.
- Template Parameters
-
- Returns
- Held object
