Previous returns the previous element in the sequence that comes before the given element. The bool returns is false if there is no previous item (i.e

ResultWithoutAST returns a parse result that has no AST. All methods for looking up AST nodes return a placeholder node that contains only the filenam

UnknownPos is a placeholder position when only the source file name is known.

NB: If we ever add other put*Node methods, to index other kinds of elements in the descriptor proto hierarchy, we need to update the index recreation

AsInt32 range checks the given int value and returns its value is in the range or 0, false if it is outside the range.
