DelayedSeriesFromValueLoaderK, V Method (K, K, FSharpFuncTupleK, BoundaryBehavior, FSharpFuncTupleK, BoundaryBehavior, FSharpAsyncIEnumerableKeyValuePairK, V)
An F#-friendly function that creates lazily loaded series. The method requires the overall range of the series (smallest and greatest key) and a function that loads the data. The function is called with two tuples that specify lower and upper boundary. It returns an asynchronous workflow that produces the data. ## Parameters - `min` - The smallest key that should be present in the created series. - `min` - The greatests key that should be present in the created series. - `loader` - A function which returns an asynchronous workflow that loads the data in a specified range. The function is called with two tuples consisting of key and `BoundaryBehavior` values. The keys specify lower and upper boundary and `BoundaryBehavior` values can be either `Inclusive` or `Exclusive`. ## Remarks For more information see the [lazy data loading tutorial](../lazysource.html).
