You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: context_composite_executor_service.rb
    path of file: ./repos/dd-trace-rb/lib/datadog/tracing/contrib/concurrent_ruby
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'concurrent/executor/executor_service'

module Datadog
  module Tracin
    
          def post(*args, &task)
            digest = Tracing.active_trace && Tracing.active_trace.to_digest
            executor = @composited_executor.is_a?(Symbol) ? Concurrent.executor(@composited_executor) : @composited_executor

            # Pass the original arguments to the composited executor, which
            # pushes them (possibly transformed) as block args
            executor.post(*args) do |*block_args|
              Tracing.continue_trace!(digest)

              # Pass the executor-provided block args as they should have been
              # originally passed without composition, see ChainPromise#on_resolvable
              yield(*block_args)
            end
          end
