How to configure Bash Completion on Mac for Docker and Docker-Compose

Copied from the official Docker-for-mac documentation (thanks Brett for the updated doc pointer):

Install shell completion

Docker Desktop for Mac comes with scripts to enable completion for the docker, docker-machine, and docker-compose commands. The completion scripts may be found inside Docker.app, in the Contents/Resources/etc/ directory and can be installed both in Bash and Zsh.

Bash

Bash has built-in support for completion To activate completion for Docker commands, these files need to be copied or symlinked to your bash_completion.d/ directory. For example, if you installed bash via Homebrew:

use std::{time, thread};

fn main() {
    let n1 = 1200;
    let n2 = 1000;

    // spawn で子スレッドを立ち上げ、子スレッドで重い処理を実行する
    // 変数 child がスレッドへのハンドルに束縛される
    // let child = thread::spawn(move || {
    //     // 重い処理を実行する

You tried to use a type which doesn't implement some trait in a place which expected that trait.

何らかの trait を実装していない型を、その trait を期待していた場所で使おうとしました

Erroneous code example:

// here we declare the Foo trait with a bar method
// ここで Foo trait を bar メソッドと共に宣言しています

require 'set'
require 'benchmark'

Benchmark.bm 10 do |r|
  limit = 65535*1000
  r.report "to_a" do
    (1..limit).to_a
  end
  r.report "to_set" do
    (1..limit).to_set
