noexcept keyword research

Examples

1. noexcept

some great example to play around.

2. Exceptions should not be thrown in "noexcept" functions

noexcept is a specifier that can be applied to a function declaration to state whether or not this function might throw an exception.

This specifier is a crucial information for the compiler as it enables it to perform automatic optimizations. It is also used by the noexcept operator, so that a developer can know whether an expression can throw, and adapt the code accordingly (for instance, to decide to move or copy an object).

3. When to Use noexcept And When to Not

In C++ 11, a new keyword noexcept is introduced. Being a replacement of deprecated throw(), what is noexcept good for? When should it be used and when should be avoided?.

4. C++ keywords: noexcept (since C++11)

Usage

1. noexcept operator
2. noexcept specifier.
5. noexcept specifier (since C++11)

Specifies whether a function could throw exceptions...

6. When should I really use noexcept?

The noexcept keyword can be appropriately applied to many function signatures, but I am unsure as to when I should consider using it in practice. Based on what I have read so far, the last-minute addition of noexcept seems to address some important issues that arise when move constructors throw. However, I am still unable to provide satisfactory answers to some practical questions that led me to read more about noexcept in the first place..

7. noexcept (C++)

C++11: Specifies whether a function might throw exceptions..

8. C++ Core Guidelines: The noexcept Specifier and Operator

If you skim through the remaining rules to error handling, you often read the word noexcept. Before I write about the rules to error handling, I write first about the noexcept specifier and the noexcept operator in this post...

9. 20.9 — Exception specifications and noexcept

n C++, all functions are classified as either non-throwing (do not throw exceptions) or potentially throwing (may throw an exception)..

10. noexcept specifier (since C++11)

Specifies whether a function will throw exceptions or not..
