Patterns and anti-patterns of Golang function error handling
Article Introduction:Go function error handling modes include: using errors.New() to create errors, wrapping underlying errors, and returning nil to indicate no errors. Anti-patterns include using magic numbers or strings to represent errors, handling errors implicitly, ignoring errors, and delayed exit patterns. Best practice: Use errors.New() to create and return errors. Anti-pattern example: Ignore errors returned by os.Open(). Following best practices and avoiding anti-patterns results in clear, maintainable, and easy-to-debug code.

Error handling mode of golang function
Article Introduction:Common patterns for handling function errors in Go are: Return error: The function returns an error value, which is nil on success and error type on failure. Global variables: Use global variables to store error values so that functions can easily access and use the error values. Panic: Used when the error is so serious that the function cannot continue to run. The function is terminated immediately and the error is propagated to the caller. Delay: Use the defer statement to execute code before the function returns, suitable for delaying cleanup operations or error handling until the end of the function.
