std::formatter<std::basic_stacktrace>

template< class Allocator >
struct formatter<std::basic_stacktrace<Allocator>>;

The template specialization of std::formatter for std::basic_stacktrace<Allocator> allows users to convert a stacktrace object to string using formatting functions such as std::format.

No format specifier is allowed.

A stacktrace object s is formatted as if by copying std::to_string(s) to the output.

Example

#include <format>
#include <iostream>
#include <stacktrace>
 
int main()
{
    auto trace = std::stacktrace::current();
    std::cout << std::format("{}\n", trace);
}
