# IGraphDispatcher

[<Interface>]
type IGraphDispatcher =
    abstract member Post (drain: Action) : unit

| | | |---|---| | Assembly | `Ranvier` | Wakes the graph when work arrives from another thread: `Post` receives a request to drain the graph's inbox. The work stays in the inbox, and the dispatcher chooses the thread the drain runs on. Under `Guarded`, a drain off the owning thread raises `InvalidOperationException` to the `Graph.Dispatch` caller and the work stays queued. Under `Unchecked`, a dispatcher that drains off-thread, such as `ImmediateDispatcher`, runs graph code there. Under `Serialised`, a drain that finds another thread inside the graph leaves the work for that thread's exit to post. ## Methods
