PreFetchFirstElementEnumerable

Library that provides a wrapper around an existing IEnumerable<T> which immediately pre-fetches the first element of the source. This means that any up-front initiation code is executed immediately, rather than when later iterated over, but retains the lazy streaming nature of the IEnumerable<T> for all later elements.

An example practical use-case could be initiating the SQL Query backing an EntityFramework streamed query.

Example Usage

public void Example(IEnumberable<int> inputEnumerable)
{
  var prefetchedEnumerable = new PreFetchFirstElementEnumerable<int>(inputEnumerable);
  var alternatePrefetchEnumerable = inputEnumerable.InitiatePrefetchOfFirstElement();
  var anotherEnumerableWithExplicitTyping = inputEnumerable.InitiatePrefetchOfFirstElement<int>();
}

public void UntypedExample(IEnumberable inputUntypedEnumerable)
{
  IEnumerable<object> prefetchedEnumerable = new PreFetchFirstElementEnumerable<object>(inputEnumerable.Cast<object>);
  IEnumerable<object> aDifferentEnumerable = inputEnumerable.InitiatePrefetchOfFirstElement();
