Types

type Context

type Context struct {
	Context  context.Context // request context passed when query executed
	Location *ast.Location   // location of print call
}

Context provides the Hook implementation context about the print() call.

type Hook

type Hook interface {
	Print(Context, string) error
}

Hook defines the interface that callers can implement to receive print statement outputs. If the hook returns an error, it will be surfaced if strict builtin error checking is enabled (otherwise, it will not halt execution.)
