Module fst::raw

Operations on raw finite state transducers.

This sub-module exposes the guts of a finite state transducer. Many parts of it, such as construction and traversal, are mirrored in the set and map sub-modules. Other parts of it, such as direct access to nodes and transitions in the transducer, do not have any analog.

Overview of types

Fst is a read only interface to pre-constructed finite state transducers. Node is a read only interface to a single node in a transducer. Builder is used to create new finite state transducers. (Once a transducer is created, it can never be modified.) Stream is a stream of all inputs and outputs in a transducer. StreamBuilder builds range queries. OpBuilder collects streams and executes set operations like union or intersection on them with the option of specifying a merge strategy for output values.

Most of the rest of the types are streams from set operations.
