Use errors.Is to check if an error matches a specific target or wraps it in Go.
Use errors.Is(err, target) to check if err is equal to target or wraps it, returning a boolean result. This function traverses the error chain to find matches even when the target error is nested inside a wrapped error.
if errors.Is(err, ErrInsecurePath) {
// Handle the specific error
}
errors.Is in Go checks if a specific error occurred, even if it was hidden inside another error message. Think of it like checking if a specific ingredient is in a complex recipe, regardless of how many other ingredients were added on top. You use it when you need to handle a known problem that might be reported indirectly by your code.
