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: with_pool.go
    path of file: ./repos/athens/pkg/download/addons
    
    the code of the file until where you have to start completion: package addons

import (
	"context"

	"github.com/gomods/athens/pkg/download"
	"github.com/gomods/athens/pkg/errors"
	"github.com/gomods/athens/pk
    
func (p *withpool) Info(ctx context.Context, mod, ver string) ([]byte, error) {
	const op errors.Op = "pool.Info"
	var info []byte
	var err error
	done := make(chan struct{}, 1)
	p.jobCh <- func() {
		info, err = p.dp.Info(ctx, mod, ver)
		close(done)
	}
	<-done
	if err != nil {
		return nil, errors.E(op, err)
	}
	return info, nil
}
