Internal representation of finite-state transducer rewrite rules used in compiling morphotactics FST. Lexicon entries (from TSV files under //src/analyzer/lexicon/base) and morphotactics model (from txt files under //src/analyzer/morphotactics/model) are validated and parsed into RewriteRule objects throughout text FST compilation in //src/analyzer/morphotactics/model_compile.py. This is basically the structured representation of the AT&T FSM format.

Used in: RewriteRuleSet

• optional string from_state = 1

  source state.

• optional string to_state = 2

  destination state.

• optional string input = 3

  arc label on input tape.

• optional string output = 4

  arc label on output tape.

Ad hoc container of rewrite rules. Mainly used to conveniently consume serialized arrays of rewrite rules in unit tests of //src/analyzer/lexicon and //src/analyzer/morphotactics submodules.

• repeated RewriteRule rule = 1
