pipe

Pipe provides reader and writer IOs, similar to IO.pipe. The main difference is that IO.pipe uses kernel-level file descriptors, but Pipe::Reader and Pipe::Writer live entirely in user-space. This avoids consuming file descriptors on systems where they are limited and ends up being much lighter weight.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     pipe:
       github: jgaskins/pipe

2. Run shards install

Usage

require "pipe"

reader, writer = Pipe.create

spawn do
  # Avoid generating the entire JSON blob in RAM
  JSON.build writer do |json|
    json.array do
      10_000_000.times do |i|
        json.scalar i
      end
    end
  end
ensure
  writer.close
end

HTTP::Client.post "http://localhost:3000/data", body: reader
