Overview ¶
Package httpwriter preserves optional net/http response-writer capabilities across instrumentation wrappers without advertising capabilities that the underlying writer does not provide.

Functions ¶
func Preserve ¶
func Preserve(base http.ResponseWriter, unwrap Unwrapper, features Features) http.ResponseWriter
Preserve returns a writer with exactly the supplied optional interfaces. The explicit combinations are necessary because Go method sets are static; wrapping a dynamic http.ResponseWriter interface would otherwise hide the capabilities it carries.
Types ¶
type CloseNotifier ¶
type CloseNotifier interface {
CloseNotify() <-chan bool
}
CloseNotifier preserves the legacy method still required by Gin's response writer without making new application code depend on net/http's deprecated named interface. The identical method set remains assignment-compatible.
type Features ¶
type Features struct {
Flusher http.Flusher
Hijacker http.Hijacker
Pusher http.Pusher
ReaderFrom io.ReaderFrom
CloseNotifier CloseNotifier
}
Features contains capability-specific delegates. A nil field means the wrapped writer does not provide that optional interface.
type Unwrapper ¶
type Unwrapper interface {
Unwrap() http.ResponseWriter
}
Unwrapper is the interface understood by http.ResponseController.
