template<class Allocator> std::string to_string(conststd::basic_stacktrace<Allocator>& st); | (since C++23) | |
Returns a string with a description ofst
.

A string with a description ofst
.
May throw implementation-defined exceptions.
Custom allocators support for this function is not provided, because the implementations usually require platform specific allocations, system calls and a lot of CPU intensive work, while a custom allocator does not provide benefits for this function as the platform specific operations take an order of magnitude more time than the allocation.
