type GeneratorOpts

type GeneratorOpts struct {
	// FormatImports, if set to true, will be used
	// call imports.Process
	FormatImports bool

	// Template will be used to generate the wrapper
	// If this is null TemplateStr or TemplatePath
	// will be used.
	Template *template.Template

	// TemplateStr will be used to generate the wrapper
	// If this is null Template or TemplatePath
	// will be used.
	TemplateStr string

	// TemplatePath will be used to generate the wrapper
	// The code will first read the contents. If this is
	// null Template or TemplateStr will be used.
	// TODO can this be a directory?
	TemplatePath string

	// Suffix will be used to name the generated wrapper.
	// GOFILE.Suffix.go. By default promwrapgen will be used.j
	Suffix string

	// Metrics will be used to decided what metrics to include.
	// Possible values are:
	// 1. duration
	// 2. total
	// 3. error
	// 4. success
	// 5. all
	// If all is specified then others will be ignored.
	Metrics types.Strings
}
