例如,在下面的代码中,Go实际上会复制goroutines生产者和消费者之间的所有largeStruct数据吗？

package main

import (
    "fmt"
    "sync"
)

type largeStruct struct {
    buf [10000]int
}

func main() {
    ch := make(chan largeStruct)
    wg := &sync.WaitGroup{}
    wg.Add(2)
    go consumer(wg,ch)
    go producer(wg,ch)
    wg.Wait()
}

func producer(wg *sync.WaitGroup,output chan<- largeStruct) {
    defer wg.Done()
    for i := 0; i < 5; i++ {
        fmt.Printf("producer: %d\n",i)
        output <- largeStruct{}
    }
    close(output)
}

func consumer(wg *sync.WaitGroup,input <-chan largeStruct) {
    defer wg.Done()
    i := 0
LOOP:
    for {
        select {
        case _,ok := <-input:
            if !ok {
                break LOOP
            }
            fmt.Printf("consumer: %d\n",i)
            i++
        }
    }
}
