For example, a package /a/b/c/internal/d/e/f can only be imported by code in the directory tree rooted at /a/b/c. It cannot be imported by code in /a/b/g or in any other repository.
bytes<->string without allocation. However, bytes can't be changed.
// StringToBytes converts string to byte slice without a memory allocation.
// The bytes must not be modified; doing so can cause
// the program to crash or behave unpredictably.
func StringToBytes(s string) []byte {
return unsafe.Slice(unsafe.StringData(s), len(s))
}
Kubebuilder does not exist as an example to copy-paste, but instead provides powerful libraries and tools to simplify building and publishing Kubernetes APIs from scratch. It provides a plugin architecture allowing users to take advantage of optional helpers and features.
Kubebuilder is developed on top of the controller-runtime and controller-tools libraries.
Kubebuilder is extensible and can be used as a library in other projects. Operator-SDK is a good example of a project that uses Kubebuilder as a library.
