Struct rustfst::algorithms::compose::FstAddOn

pub struct FstAddOn<F, T> { /* private fields */ }

Adds an object of type T to an FST. The resulting type is a new FST implementation.

Trait Implementations

impl<F: Clone, T: Clone> Clone for FstAddOn<F, T>

fn clone(&self) -> FstAddOn<F, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Semiring, F: CoreFst<W>, T> CoreFst<W> for FstAddOn<F, T>

type TRS = <F as CoreFst<W>>::TRS

Weight use in the wFST. This type must implement the Semiring trait.

fn start(&self) -> Option<StateId>

Returns the ID of the start state of the wFST if it exists else none.

fn final_weight(&self, state_id: StateId) -> Result<Option<W>>

Retrieves the final weight of a state (if the state is a final one).

unsafe fn final_weight_unchecked(&self, state_id: StateId) -> Option<W>

Retrieves the final weight of a state (if the state is a final one).

fn num_trs(&self, s: StateId) -> Result<usize>

Number of trs leaving a specific state in the wFST.

unsafe fn num_trs_unchecked(&self, s: StateId) -> usize

Number of trs leaving a specific state in the wFST.

fn get_trs(&self, state_id: StateId) -> Result<Self::TRS>

Get an iterator on the transitions leaving state state.

unsafe fn get_trs_unchecked(&self, state_id: StateId) -> Self::TRS

Get an iterator on the transitions leaving state state.

fn properties(&self) -> FstProperties

Retrieve the FstProperties stored in the Fst. As a result, all the properties returned are verified by the Fst but some other properties might be true as well despite the flag not being set.

fn num_input_epsilons(&self, state: StateId) -> Result<usize>

Returns the number of trs with epsilon input labels leaving a state.

fn num_output_epsilons(&self, state: StateId) -> Result<usize>

Returns the number of trs with epsilon output labels leaving a state.

fn is_final(&self, state_id: StateId) -> Result<bool>

Returns whether or not the state with identifier passed as parameters is a final state.

unsafe fn is_final_unchecked(&self, state: StateId) -> bool

Returns whether or not the state with identifier passed as parameters is a final state.

fn is_start(&self, state_id: StateId) -> bool

Check whether a state is the start state or not.

fn properties_with_mask(&self, mask: FstProperties) -> FstProperties

Apply a mask to the FstProperties returned.

fn properties_check(&self, props_known: FstProperties) -> Result<FstProperties>

Retrieve the FstProperties in the Fst and check that all the properties in props_known are known (not the same as true). If not an error is returned.

impl<F: Debug, T: Debug> Debug for FstAddOn<F, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<W, F, T> ExpandedFst<W> for FstAddOn<F, T>

where W: Semiring, F: ExpandedFst<W>, T: Debug + Clone + PartialEq,

fn num_states(&self) -> usize

Returns the number of states that contains the FST. They are all counted even if some states are not on a successful path (doesn’t perform triming).

fn states_range(&self) -> Range<StateId>

fn approx_equal<F2: ExpandedFst<W>>(&self, fst2: &F2, delta: f32) -> bool

impl<W, F, T: Debug> Fst<W> for FstAddOn<F, T>

where W: Semiring, F: Fst<W>,

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.

fn final_states_iter(&self) -> FinalStatesIterator<'_, W, Self>

where Self: Sized,

Returns an Iterator on the final states along with their weight.

fn paths_iter(&self) -> PathsIterator<'_, W, Self>

where Self: Sized,

Returns an Iterator on the paths accepted by the Fst.

fn string_paths_iter(&self) -> Result<StringPathsIterator<'_, W, Self>>

where Self: Sized,

Returns an Iterator on the paths accepted by the Fst. Plus, handles the SymbolTable allowing to retrieve the strings instead of only the sequence of labels.

impl<W, F, T> FstIntoIterator<W> for FstAddOn<F, T>

where W: Semiring, F: FstIntoIterator<W>, T: Debug,

type TrsIter = <F as FstIntoIterator<W>>::TrsIter

type FstIter = <F as FstIntoIterator<W>>::FstIter

fn fst_into_iter(self) -> Self::FstIter

impl<'a, W, F, T> FstIterator<'a, W> for FstAddOn<F, T>

where W: Semiring + 'a, F: FstIterator<'a, W>,

impl<F: PartialEq, T: PartialEq> PartialEq for FstAddOn<F, T>

fn eq(&self, other: &FstAddOn<F, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, F: StateIterator<'a>, T> StateIterator<'a> for FstAddOn<F, T>

type Iter = <F as StateIterator<'a>>::Iter

Iterator used to iterate over the state_id of the states of an FST.

fn states_iter(&'a self) -> Self::Iter

Creates an iterator over the state_id of the states of an FST.
