Method HandleError

handler.go:107–111

HandleError registers a Handler for a specific error value. Multiple calls with the same error value override previous calls. As a special case, a nil error value registers a Handler for any error that doesn't have a specific Handler.

(err error, h Handler)

// error value registers a Handler for any error that doesn't have a specific
// Handler.
func (mux *Mux) HandleError(err error, h Handler) {
	mux.mu.Lock()
	defer mux.mu.Unlock()
	mux.errm[err] = h
}

// HandleErrors registers a Handler for any error that doesn't have a specific
// Handler.
