Struct rustfst::FstPath

pub struct FstPath<W: Semiring> {
    pub ilabels: Vec<Label>,
    pub olabels: Vec<Label>,
    pub weight: W,
}

Structure representing a path in a FST (list of input labels, list of output labels and total weight).

Fields

ilabels: Vec<Label>

List of input labels.

olabels: Vec<Label>

List of output labels.

weight: W

Total weight of the path computed by multiplying the weight of each transition.

Implementations

impl<W: Semiring> FstPath<W>

pub fn new(ilabels: Vec<Label>, olabels: Vec<Label>, weight: W) -> Self

Creates a new Path.

pub fn add_to_path(
    &mut self,
    ilabel: Label,
    olabel: Label,
    weight: &W
) -> Result<()>

Adds the content of an FST transition to the Path. Labels are added at the end of the corresponding vectors and the weight is multiplied by the total weight already stored in the Path.

pub fn add_weight(&mut self, weight: &W) -> Result<()>

Add a single weight to the Path by multiplying the weight by the total weight of the path.

pub fn concat(&mut self, other: FstPath<W>) -> Result<()>

Append a Path to the current Path. Labels are appended and weights multiplied.

pub fn is_empty(&self) -> bool

Trait Implementations

impl<W: Clone + Semiring> Clone for FstPath<W>

fn clone(&self) -> FstPath<W>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<W: Debug + Semiring> Debug for FstPath<W>

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

Formats the value using the given formatter.

impl<W: Semiring> Default for FstPath<W>

fn default() -> Self

impl<W: Semiring + Hash + Eq> Eq for FstPath<W>

impl<W: Semiring + Hash + Eq> Hash for FstPath<W>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

fn partial_cmp(&self, other: &FstPath<W>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &FstPath<W>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &FstPath<W>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &FstPath<W>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &FstPath<W>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
