std::error_code - cppreference.com
std::error_code is a platform-dependent error code. Each std::error_code object holds an error code originating from the operating system or some low-level interface and a pointer to an object of type std::error_category, which corresponds to the said interface.
Standard error - Wikipedia
The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation.

Example 2: std.error Function [plotrix R Package]. You don't want to create a function yourself? The plotrix add-on package includes the std.error function, which is also able to calculate the standard error of the mean. First, let's install and load the plotrix package
std::system_error - cppreference.com
std::system_error is the type of the exception thrown by various library functions (typically the functions that interface with the OS facilities, e.g. the constructor of std::thread) when the exception has an associated std::error_code, which may be reported.
std::error::Error - Rust
Error::source() is generally used when errors cross "abstraction boundaries". If one module must report an error that is caused by an error from a lower-level module, it can allow accessing that error via Error::source(). This makes it possible for the high-level module to provide its own errors while also...

Error handling in the C++ language | C++ - don't panic!
Error handling now and tomorrow. So we will be talking about the error handling. Well first, I guess I need to explain myself why I decided to talk about You all know about error handling mechanisms in the C++ language right? You know you can throw exceptions, you know you shouldn't throw them too...
Error Handling and std::optional
In my last two posts in the C++17 STL series, I covered how to use std::optional. This wrapper type (also called "vocabulary type") is handy when you'd like to express that something is 'nullable' and might be 'empty'.

std::domain_error. This is an exception thrown when a mathematically invalid domain is used. std::underflow_error. This is thrown if a mathematical underflow occurs. Define New Exceptions.
std::runtime_error - cppreference.com
Exceptions of type std:runtime_error are thrown by the following standard library components: std::locale::locale and std::locale::combine. In addition, the standard exception types std::range_error, std::overflow_error, std::underflow_error, std::regex_error, and std::system_error are derived from...
API documentation for the Rust `Error` trait in crate `std`.
A short description of the error. The description should only be used for a simple message. It should not contain newlines or sentence-ending punctuation, to facilitate embedding in larger user-facing strings. For showing formatted error messages with more information see Display.
std::make_error_condition(std::errc) - cppreference.com
Creates an error condition for an errc value e. Sets the error code to int(e) and error category to std::generic_category.
C++ Errors: Undefined Reference, Unresolved External Symbol etc.
This Tutorial Details the Critical Errors that Programmers often Encounter in C++like Undefined Reference, a Segmentation Fault (core dumped) and We will discuss the most important errors that we often encounter in C++ that are equally critical indeed. Apart from the system and semantic errors...
std::overflow_error - cppreference.com
Because copying std::overflow_error is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string. This is also why there is no constructor taking std::string&&: it would have to copy the content anyway.
