# class Psych::Stream

Psych::Stream is a streaming YAML emitter. It will not buffer your YAML, but send it straight to an IO.

Here is an example use:

    stream = Psych::Stream.new($stdout)
    stream.start
    stream.push({:foo => 'bar'})
    stream.finish

YAML will be immediately emitted to $stdout with no buffering.

Psych::Streaming#start will take a block and ensure that Psych::Visitors::YAMLTree#finish is called, so you can do this form:

    stream = Psych::Stream.new($stdout)
    stream.start do |em|
      em.push(:foo => 'bar')
    end
