Why I Prefer Exceptions to Error Values
Why I Prefer Exceptions to Error Values
Good error handling is key to robust programs, but often dreaded by programmers because there is always one more edge case. Traditional object-oriented programming languages use special exception classes that can be thrown to break the regular control flow for immediate error reporting. Let’s take a quick look at an example that explores error-safe integer division:
int safeDiv(int a, int b) {
if (b == 0)
throw Div0(); // Exceptions are passed out-of-line
return a / b; // Totally safe now, right?
}
Newer languages tend to favor functional-style error reporting and encode errors in their return type:
For example, Go encodes the error in the return type with an (res, err) tuple, and Rust returns Result<T, E>, a sum type of result and error.
Even older languages such as C++ now include error values in their standard library with std::expected:

LFX Mentorship Journey
Introduction # This summer, I had the incredible opportunity to participate in the LFX Mentorship program, where I contributed to Vitess, a CNCF graduated project. Vitess is a cloud-native database designed for horizontal scaling of MySQL. My specific focus during this mentorship was on the "Arewefastyet" subproject, an essential benchmarking platform for Vitess. "Arewefastyet" plays a crucial role in ensuring that each new version of Vitess maintains or improves performance, making it a vital component of the Vitess ecosystem.
