Constructs an empty basic_stacktrace , or copy/move from other .

1) Default constructor. Constructs an empty basic_stacktrace with a default-constructed allocator.
2) Constructs an empty basic_stacktrace using alloc as the allocator.
3) Copy constructor. Constructs a basic_stacktrace with the copy of the contents of other , the allocator is obtained as if by calling std:: allocator_traits < allocator_type > :: select_on_container_copy_construction ( other. get_allocator ( ) ) .
4) Move constructor. Constructs a basic_stacktrace with the contents of other using move semantics. Allocator is move-constructed from that of other . After construction, other is left in a valid but unspecified state.
5) Same as the copy constructor, except that alloc is used as the allocator.
6) Behaves same as the move constructor if alloc == other. get_allocator ( ) . Otherwise, allocates memory with alloc and performs element-wise move. alloc is used as the allocator.

(3,5,6) may throw an exception or construct an empty basic_stacktrace on allocation failure.

Contents

Parameters

alloc - allocator to use for all memory allocations of the constructed basic_stacktrace
other - another basic_stacktrace to copy/move from

Exceptions

1)
noexcept specification:
noexcept ( std:: is_nothrow_default_constructible_v < allocator_type > )
3,5,6) May propagate the exception thrown on allocation failure.

Complexity

1,2) Constant.
3) Linear in size of other .
4) Constant.
5) Linear in size of other .
6) Linear in size of other if alloc ! = other. get_allocator ( ) , otherwise constant.

Notes

After container move construction (overload ( 4 ) ), references, pointers, and iterators (other than the end iterator) to other remain valid, but refer to elements that are now in * this . The current standard makes this guarantee via the blanket statement in [container.reqmts]/67 , and a more direct guarantee is under consideration via LWG issue 2321 .
