std::stacktrace_entry::source_line

Since C++23

Returns a 1-based line number that lexically relates to the evaluation represented by *this, or 0 on failure other than allocation failure, e.g. when *this is empty.

# Declarations

std::uint_least32_t source_line() const;

(since C++23)

# Return value

The line number specified above on success, 0 on failure other than allocation failure.

# Notes

The presumed line number is what the predefined macro LINE expands to, and can be changed by the #line directive.

This function is not required to be noexcept because getting source line requires allocation on some platforms.
