Current solution borrows ideas from C#:
```C#
using System.Threading.Channels;
var channel = Channel.CreateBounded<int>(2);
_ = Task.Run(async () =>
{
try
{
for (var i = 1; i <= 3; i++)
{
if (i == 3)
throw new InvalidOperationException("sensor failed");
await channel.Writer.WriteAsync(i * i);
}
channel.Writer.Complete();
}
catch (Exception failure)
{
channel.Writer.Complete(failure);
}
});
var seen = new List<int>();
try
{
await foreach (var value in channel.Reader.ReadAllAsync())
seen.Add(value);
}
catch (InvalidOperationException e)
{
Console.WriteLine(e.Message); // sensor failed
}
// seen == [1, 4]
```
