/// All available field id representations of the base `Model` struct.
///
/// Most can be parsed as `ModelFieldId` and used to query a Model. Some are
/// parameterized field ids (with angle bracketed variable like <idx>) that must
/// have the variable substituted with specific values to be parsed correctly.
///
/// For example, <idx> must be some zero-indexed Vec index, <cgroup_path> must
/// be a path and <key> could be pid, disk name, iface name etc.
///
/// This list also servers as documentation for available field ids that could
/// be used in other below crates. A test ensures that this list is up-to-date.
