// Context is complementary to Sandbox. This is an ordered list of
// contexts to which an interface is allowed to be vended by other
// mojo interfaces. Restricted interfaces are annotated with the RequireContext
// attribute. Vending methods are annotated with the AllowedContext attribute.
// If an interface is marked with RequireContext it can only be vended by
// methods with a corresponding AllowedContext of the same type value or lower.
// Do not mark this enum as Extensible or Stable.
enum Context {
  // This should always be the first value. It corresponds only to the browser
  // process in Chromium and should not be assigned to other utilities, even
  // if they are unsandboxed.
  kBrowser,
  // Utilities that are allowed to receive privileged interfaces. Note that
  // this may not correspond to a sandbox level - sometimes it is possible to
  // tightly sandbox an otherwise privileged utility.
  kPrivilegedUtility,
  // This should always be the last value. Renderers and most services (however
  // they are sandboxed) will fall into this category.
