package cgozstd
// This file contains placeholder types and funcs so that the package still
// builds (with the same API) when CGO_ENABLED=0. The package doesn't work
// without cgo, but it will fail at run time, not compile time.
//
// In particular, the build stays green regardless of whether CGO_ENABLED is on
// or off. Installing and testing every package in the whole repository will
// not fail. The tests in this package don't pass, but they are skipped.
