std::to_string

Since C++23

Header: <stacktrace>

Returns a string with a description of f.

# Declarations

std::string to_string( const std::stacktrace_entry& f );

(since C++23)

# Parameters

f: a stacktrace_entry whose description is to be returned

# Return value

A string with a description of f.

# Notes

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.

# Example

#include <stacktrace>
#include <string>
#include <iostream>
 
int main()
{
    auto st = std::stacktrace::current();
    std::cout <<
        "Description of an empty stacktrace entry:\n" +
        std::to_string(std::stacktrace_entry{}) << '\n';
    if (st.size() > 0) {
        std::cout <<
            "Description of a non-empty stacktrace entry:\n" +
            std::to_string(st[0]) << '\n';
    }
}
