fn new() !FdNotifier

new creates a new KqueueNotifier. The FdNotifier interface is returned to allow OS specific implementations without exposing the concrete type

fn FdConfigFlags.from[W](input W) !FdConfigFlags

from returns the FdConfigFlags value of an integer or of a field name, or an error if there is none.

fn FdConfigFlags.zero() FdConfigFlags

zero returns a FdConfigFlags value with no flags set.

fn FdEventType.from[W](input W) !FdEventType

from returns the FdEventType value of an integer or of a field name, or an error if there is none.

fn FdEventType.zero() FdEventType

zero returns a FdEventType value with no flags set.

interface FdEvent {
	fd   int
	kind FdEventType
}

interface FdNotifier {
mut:
	add(fd int, events FdEventType, conf ...FdConfigFlags) !
	modify(fd int, events FdEventType, conf ...FdConfigFlags) !
	remove(fd int) !
	wait(timeout time.Duration) []FdEvent
	close() !
}

Backends should provide a new()?FdNotifier function
