Aqueduct provides some useful, albeit niche, utilities for working with streams and pipes.

Allows you to read from a single pipe or stream into multiple targets. This is useful for cases where you can't buffer the original stream into memory or you're working with a source you can't seek. Internally it uses individual pipes per target to allow independent processing and minimal memory overhead.

Each bifurcation target has individual options for:

• The reader which processes the data
• An exception handler triggered on failure of any target
• Control of the number of bytes for blocking/resuming writes to the target
• The maximum number of bytes to write to the specific target

Additionally, the bifurcation process overall has options for:

• The minimum read buffer size of the source pipe or stream
• Whether to leave the stream open after bifurcation
• Allow exceptions from readers to bubble out to the calling code
• Cancellation token for reading/writing process

Example usage of pipe/stream bifurcation:

await myStream.BifurcatedReadAsync(
	new BifurcationTargetConfig(
		async (Stream stream, CancellationToken cancellationToken) =>
		{
			using var fileStream = File.OpenWrite("some-file-path.bin");
			await stream.CopyToAsync(fileStream);
		},
		maxTotalBytes: 1024
	),
	new BifurcationTargetConfig(
		async (PipeReader reader, CancellationToken cancellationToken) =>
		{
			await someService.ProcessData(reader);
		}
	)
);
