type Printer ¶

type Printer interface {
	// ReplaceArg is a function that may be called to replace arguments to
	// errors. This is mostly used for cycle detection.
	ReplaceArg(x any) (r any, wasReplaced bool)
}

Printer is the interface used to print CUE values. The only implementation so far is the one in internal/core/debug. Note that most packages cannot directly import the debug package.
