Ordering between field paths is primarily to provide canonical orderings for sets of
paths, for example in a FieldMask. This ordering is performed segment-wise,
using ordinal string comparisons.
Constructors
FieldPath(params string[])
public FieldPath(params string[] segments)
Creates a path from multiple segments. Each segment is treated verbatim: it may contain dots, which will lead to the segment being escaped in the
path's string representation.
