		Package godebug makes the settings in the $GODEBUG environment variable
		available to other packages. These settings are often used for compatibility
		tweaks, when we need to change a default behavior but want to let users
		opt back in to the original. For example GODEBUG=http2server=0 disables
		HTTP/2 support in the net/http server.
		
		In typical usage, code should declare a Setting as a global
		and then call Value each time the current setting value is needed:
		
			var http2server = godebug.New("http2server")
		
			func ServeConn(c net.Conn) {
				if http2server.Value() == "0" {
					disallow HTTP/2
					...
				}
				...
			}


Package-Level Type Names (only one)


	/* sort by:  |  */
	
		A Setting is a single setting in the $GODEBUG environment variable.

		
			
				Name returns the name of the setting.

			
				String returns a printable form for the setting: name=value.

			
				Value returns the current value for the GODEBUG setting s.
				
				Value maintains an internal cache that is synchronized
				with changes to the $GODEBUG environment variable,
				making Value efficient to call as frequently as needed.
				Clients should therefore typically not attempt their own
				caching of Value's result.
