Unfortunately there isn't a good solution at the moment. Basically you have to add a task to tasks.json, which begins like this:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558 
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "type": "cargo",
      "subcommand": "check",
      "problemMatcher": [
        "$rustc"
      ]
    },
    {
      "type": "cargo",
      "subcommand": "build",
      "problemMatcher": [
        "$rustc"
      ]
    }
  ]
}

A.R. suggested adding another identical entry but with "subcommand": "run" but it doesn't work. You get this error:

Error: The cargo task detection didn't contribute a task for the following configuration:
{
    "type": "cargo",
    "subcommand": "run",
    "problemMatcher": [
        "$rustc"
    ]
}
The task will be ignored.

Instead you can add a "type": "shell" task. However this still isn't perfect because for some reason adding that task means cargo check and cargo build don't show up when you press Ctrl-Shift-B at all.

My solution is just to change those to shell tasks too, so your entire tasks.json is:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558 
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "type": "shell",
      "label": "cargo check",
      "command": "cargo",
      "args": [
          "check"
      ],
      "problemMatcher": [
          "$rustc"
      ],
      "group": "build"
    },
    {
      "type": "shell",
      "label": "cargo build",
      "command": "cargo",
      "args": [
          "build"
      ],
      "problemMatcher": [
          "$rustc"
      ],
      "group": "build"
    },
    {
      "type": "shell",
      "label": "cargo run",
      "command": "cargo",
      "args": [
          "run"
      ],
      "problemMatcher": [
          "$rustc"
      ],
      "group": "build"
    }
  ]
}
