Trait defining the minimum interface necessary for a wFST.

Required methods

fn input_symbols(&self) -> Option<&Arc<SymbolTable>>

Retrieves the input SymbolTable associated to the Fst. If no SymbolTable has been previously attached then None is returned.

fn output_symbols(&self) -> Option<&Arc<SymbolTable>>

Retrieves the output SymbolTable associated to the Fst. If no SymbolTable has been previously attached then None is returned.

fn set_input_symbols(&mut self, symt: Arc<SymbolTable>)

Attaches an output SymbolTable to the Fst. The SymbolTable is not duplicated with the use of Arc.

fn set_output_symbols(&mut self, symt: Arc<SymbolTable>)

Attaches an output SymbolTable to the Fst. The SymbolTable is not duplicated with the use of Arc.

fn take_input_symbols(&mut self) -> Option<Arc<SymbolTable>>

Removes the input symbol table from the Fst and retrieves it.

fn take_output_symbols(&mut self) -> Option<Arc<SymbolTable>>

Removes the output symbol table from the Fst and retrieves it.
