Properties
Closed
public CancellationToken Closed { get; }Gets a token cancelled after the context stops accepting work and before queued work is rejected.
Remarks
Callbacks run synchronously on the closing thread. Their exceptions are reported through RunicModelContext.UnhandledTurnException and do not interrupt shutdown. The token remains usable after disposal.
IsExecuting
public bool IsExecuting { get; }Gets whether the calling code is executing one of this context's turns.
Documentation from IRunicModelContext.IsExecuting.

InvokeAsync
public ValueTask InvokeAsync(Action turn, CancellationToken cancellationToken = default)Runs a short synchronous turn in this context.

InvokeAsync
public ValueTask<T> InvokeAsync<T>(Func<T> turn, CancellationToken cancellationToken = default)Runs a short synchronous turn in this context and returns its result.
