填充缓冲的chan直到变满或持续一段时间

Question

i have a chan string which is buffered, i keep filling it with random strings until a time.Duration passes or until it gets full.

my question is should i use a ticker for that considering that its a one time task or is there a more convienient way?

here is my current way of doing it

package main

import (
    "fmt"
    "time"
)

func main() {
    res := fillChan(time.Duration(1*time.Nanosecond), 100000)
    fmt.Println(len(res))
}

func fillChan(maxDuration time.Duration, chanSize int) chan string {
    c := make(chan string, chanSize)

    ticker := time.NewTicker(maxDuration)

    for {
        select {
        case <-ticker.C:
            ticker.Stop()
            return c
        case c <- "Random message":
        default:
            return c
        }
    }

}

I am no expert in Go (in fact, I've never used it), but the documentation suggests Timer, or After for single events.

select {
case <-time.After(1*time.Nanosecond):
    return c
case c <- "Random message":
default:
    return c
}
