Difference between `Config.unwrap` and `Config.all` in TypeScript

is there any different between the following 2:

const HostPort = Config.unwrap({
  host: Config.string('HOST'),
  port: Config.number('PORT'),
})

const HostPort = Config.unwrap({
  host: Config.string('HOST'),
  port: Config.number('PORT'),
})

const HostPort = Config.all({
  host: Config.string('HOST'),
  port: Config.number('PORT'),
})

const HostPort = Config.all({
  host: Config.string('HOST'),
  port: Config.number('PORT'),
})
