它对应原本 basic_stacktrace 的首条目之前的迭代器。此迭代器表现为占位符,试图解引用它导致未定义行为。 参数 (无) 返回值 逆向basic_stacktrace 的尾迭代器。 复杂度 常数。 示例运行此代码 #include <algorithm> #include <iostream> #include <stacktrace> int main() { auto trace = std::stacktrace::...

-- >8 -- The standard allows allocators to throw any kind of exception, not only something that can be caught as std::bad_alloc. std::basic_stracktrace was assuming std::bad_alloc. libstdc++-v3/ChangeLog: * include/std/stacktrace (basic_stacktrace::_Impl::_M_allocate): Do not assume...

对于std::thread::id和std::stacktrace_entry,见thread id 格式说明和stacktrace entry 格式说明。 对于std::basic_stacktrace,不允许使用格式说明符。 (C++23 起) 对于std::filesystem::path,见路径格式说明。 (C++26 起) 对于其他可格式化类型,格式说明由用户定义的std::formatter特化决定。
When thePrettyStreamobject is destroyed, the destructor printsstd::endlto the stream. This is neat and simple (and predatesstd::basic_stacktraceby a few years). The implementation is enclosed in theprettystreamsnamespace. Output operators forstdcontainers extend thestdnamespace. ...
