type RequestFieldExtractorFunc ¶

type RequestFieldExtractorFunc func(ctx *gin.Context) map[string]interface{}

RequestFieldExtractorFunc is a user-provided function that extracts field information from a http request. It is called from tags middleware on arrival of request. Keys and values will be added to the context tags. If there are no fields, you should return a nil.

type Tags ¶

type Tags interface {
	// Set sets the given key in the metadata tags.
	Set(key string, value interface{}) Tags
	// Has checks if the given key exists.
	Has(key string) bool
	// Values returns a map of key to values.
	// Do not modify the underlying map, please use Set instead.
	Values() map[string]interface{}
}

Tags is the interface used for storing request tags between Context calls. The default implementation is *not* thread safe, and should be handled only in the context of the request.
