为什么并发-ruby立即退出
为什么并发-ruby立即退出
提问于 2019-10-15 02:27:49
我正在尝试使用concurrent-ruby来完成一些并行任务，我正在遵循文档并使用Concurrent::Async
require 'concurrent'
class Echo
include Concurrent::Async
def echo(msg)
p msg
end
end
horn = Echo.new
horn.async.echo('one')并在终端中运行，但进程不打印任何内容，并立即退出

horn = Echo.new
# t is an instance of Concurrent::IVar which includes Concurrent::Concern::Obligation
t = horn.async.echo('one')
# wait until obligation is complete or the timeout has been reached
