/// `FieldMask` represents a set of symbolic field paths, for example:
///
/// ```text
/// paths: "f.a"
/// paths: "f.b.d"
/// ```
///
/// Here `f` represents a field in some root message, `a` and `b`
/// fields in the message found in `f`, and `d` a field found in the
/// message in `f.b`.
///
/// Field masks are used to specify a subset of fields that should be
/// returned by a get operation or modified by an update operation.
/// Field masks also have a custom JSON encoding (see below).
///
/// # Field Masks in Projections
///
/// When used in the context of a projection, a response message or
/// sub-message is filtered by the API to only contain those fields as
/// specified in the mask. For example, if the mask in the previous
/// example is applied to a response message as follows:
///
/// ```text
/// f {
///   a : 22
///   b {
///     d : 1
///     x : 2
///   }
///   y : 13
/// }
/// z: 8
/// ```
///
/// The result will not contain specific values for fields x,y and z
/// (their value will be set to the default, and omitted in proto text
/// output):
///
///
/// ```text
/// f {
///   a : 22
///   b {
///     d : 1
///   }
/// }
/// ```
///
/// A repeated field is not allowed except at the last position of a
/// paths string.
///
/// If a FieldMask object is not present in a get operation, the
/// operation applies to all fields (as if a FieldMask of all fields
/// had been specified).
///
/// Note that a field mask does not necessarily apply to the
/// top-level response message. In case of a REST get operation, the
/// field mask applies directly to the response, but in case of a REST
/// list operation, the mask instead applies to each individual message
/// in the returned resource list. In case of a REST custom method,
/// other definitions may be used. Where the mask applies will be
/// clearly documented together with its declaration in the API.  In
/// any case, the effect on the returned resource/resources is required
/// behavior for APIs.
///
/// # Field Masks in Update Operations
///
/// A field mask in update operations specifies which fields of the
/// targeted resource are going to be updated. The API is required
/// to only change the values of the fields as specified in the mask
/// and leave the others untouched. If a resource is passed in to
/// describe the updated values, the API ignores the values of all
/// fields not covered by the mask.
///
/// If a repeated field is specified for an update operation, new values will
/// be appended to the existing repeated field in the target resource. Note that
/// a repeated field is only allowed in the last position of a `paths` string.
///
/// If a sub-message is specified in the last position of the field mask for an
/// update operation, then new value will be merged into the existing sub-message
/// in the target resource.
///
/// For example, given the target message:
///
/// ```text
/// f {
///   b {
///     d: 1
///     x: 2
///   }
///   c: [1]
/// }
/// ```
///
/// And an update message:
///
/// ```text
/// f {
///   b {
///     d: 10
///   }
///   c: [2]
/// }
/// ```
///
/// then if the field mask is:
///
///  paths: \["f.b", "f.c"\]
///
/// then the result will be:
///
/// ```text
/// f {
///   b {
///     d: 10
///     x: 2
///   }
///   c: [1, 2]
/// }
/// ```
///
/// An implementation may provide options to override this default behavior for
/// repeated and message fields.
///
/// In order to reset a field's value to the default, the field must
/// be in the mask and set to the default value in the provided resource.
/// Hence, in order to reset all fields of a resource, provide a default
/// instance of the resource and set all fields in the mask, or do
/// not provide a mask as described below.
///
/// If a field mask is not present on update, the operation applies to
/// all fields (as if a field mask of all fields has been specified).
/// Note that in the presence of schema evolution, this may mean that
/// fields the client does not know and has therefore not filled into
/// the request will be reset to their default. If this is unwanted
/// behavior, a specific service may require a client to always specify
/// a field mask, producing an error if not.
///
/// As with get operations, the location of the resource which
/// describes the updated values in the request message depends on the
/// operation kind. In any case, the effect of the field mask is
/// required to be honored by the API.
///
/// ## Considerations for HTTP REST
///
/// The HTTP kind of an update operation which uses a field mask must
/// be set to PATCH instead of PUT in order to satisfy HTTP semantics
/// (PUT must only be used for full updates).
///
/// # JSON Encoding of Field Masks
///
/// In JSON, a field mask is encoded as a single string where paths are
/// separated by a comma. Fields name in each path are converted
/// to/from lower-camel naming conventions.
///
/// As an example, consider the following message declarations:
///
/// ```text
/// message Profile {
///   User user = 1;
///   Photo photo = 2;
/// }
/// message User {
///   string display_name = 1;
///   string address = 2;
/// }
/// ```
///
/// In proto a field mask for `Profile` may look as such:
///
/// ```text
/// mask {
///   paths: "user.display_name"
///   paths: "photo"
/// }
/// ```
///
/// In JSON, the same mask is represented as below:
///
/// ```text
/// {
///   mask: "user.displayName,photo"
/// }
/// ```
///
/// # Field Masks and Oneof Fields
///
/// Field masks treat fields in oneofs just as regular fields. Consider the
/// following message:
///
/// ```text
/// message SampleMessage {
///   oneof test_oneof {
///     string name = 4;
///     SubMessage sub_message = 9;
///   }
/// }
/// ```
///
/// The field mask can be:
///
/// ```text
/// mask {
///   paths: "name"
/// }
/// ```
///
/// Or:
///
/// ```text
/// mask {
///   paths: "sub_message"
/// }
/// ```
///
/// Note that oneof type names ("test_oneof" in this case) cannot be used in
/// paths.
///
/// ## Field Mask Verification
///
/// The implementation of any API method which has a FieldMask type field in the
/// request should verify the included field paths, and return an
/// `INVALID_ARGUMENT` error if any path is unmappable.
