Binder

public struct Binder<Value> : ObserverType

Observer that enforces interface binding rules:

  • can’t bind errors (in debug builds binding of errors causes fatalError in release builds errors are being logged)
  • ensures binding is performed on a specific scheduler

Binder doesn’t retain target and in case target is released, element isn’t bound.

By default it binds elements on main scheduler.

  • Declaration

    Swift

    public typealias Element = Value

  • Initializes Binder

    Declaration

    Swift

    public init<Target>(_ target: Target, scheduler: ImmediateSchedulerType = MainScheduler(), binding: @escaping (Target, Value) -> Void) where Target : AnyObject

    Parameters

    target

    Target object.
    scheduler

    Scheduler used to bind the events.
    binding

    Binding logic.

  • Binds next element to owner view as described in binding.

    Declaration

    Swift

    public func on(_ event: Event<Value>)

  • Erases type of observer.

    Declaration

    Swift

    public func asObserver() -> AnyObserver<Value>

    Return Value

    type erased observer.
