Using VSCode DevContainer for rust development

In order to develop rust inside a devcontainer , on windows with docker vm, or linux with docker, you need the below files:

🔗devcontainer.json

// For format details, see https://aka.ms/devcontainer.json. For config options, see the README at:
// https://github.com/microsoft/vscode-dev-containers/tree/v0.209.6/containers/python-3-postgres
// Update the VARIANT arg in docker-compose.yml to pick a Python version
{
  "name": "Yew Rust",
  "dockerComposeFile": "../docker/docker-compose.devel.yml",
  "service": "myapp",
  "workspaceFolder": "/workspace",
  // Set *default* container specific settings.json values on container create.
  // "settings": {
  // 	"python.defaultInterpreterPath": "/usr/local/bin/python",
  // 	"python.linting.enabled": true,
  // 	"python.linting.pylintEnabled": true,
  // 	"python.formatting.autopep8Path": "/usr/local/py-utils/bin/autopep8",
  // 	"python.formatting.blackPath": "/usr/loal/py-utils/bin/black",
  // 	"python.formatting.yapfPath": "/usr/local/py-utils/bin/yapf",

  // 	"python.linting.pylintPath": "/usr/local/py-utils/bin/pylint",
  // 	"python.testing.pytestPath": "/usr/local/py-utils/bin/pytest"
  // },
  // Add the IDs of extensions you want installed when the container is created.
  "extensions": [
   ]
  // Use 'forwardPorts' to make a list of ports inside the container available locally.
  // "forwardPorts": [
  // 	3306
  // ],
  // Use 'postCreateCommand' to run commands after the container is created.
  // "postCreateCommand": "pip install --user -r requirements.txt",
  // Comment out connect as root instead. More info: https://aka.ms/vscode-remote/containers/non-root.
