public sealed class DocumentMask : IMessage<DocumentMask>, IEquatable<DocumentMask>, IDeepCloneable<DocumentMask>, IBufferMessage, IMessage
A set of field paths on a document.
Used to restrict a get or update operation on a document to a subset of its
fields.
This is different from standard field masks, as this is always scoped to a
[Document][google.firestore.v1.Document], and takes in account the dynamic nature of [Value][google.firestore.v1.Value].
