Struct rustfst::Tr

pub struct Tr<W> {
    pub ilabel: Label,
    pub olabel: Label,
    pub weight: W,
    pub nextstate: StateId,
}

Structure representing a transition from a state to another state in a FST.

Fields

ilabel: Label

Input label.

olabel: Label

Output label.

weight: W

Weight.

nextstate: StateId

ID of the next state.

Implementations

impl<W> Tr<W>

pub fn new<S: Into<W>>(
    ilabel: Label,
    olabel: Label,
    weight: S,
    nextstate: StateId
) -> Self

Creates a new Tr.

Example

let transition = Tr::<TropicalWeight>::new(0, 1, 1.3, 2);

assert_eq!(transition.ilabel, 0);
assert_eq!(transition.olabel, 1);
assert_eq!(transition.weight, TropicalWeight::new(1.3));
assert_eq!(transition.nextstate, 2);

pub fn set_value(&mut self, tr: &Tr<W>) where
    W: Clone, 

Updates the values of the attributes of the Tr from another Tr.

Example

let mut tr_1 = Tr::<TropicalWeight>::new(0, 1, 1.3, 2);
let tr_2 = Tr::new(1, 2, 1.2, 3);

tr_1.set_value(&tr_2);

assert_eq!(tr_1, tr_2);

Trait Implementations

impl<W: Clone> Clone for Tr<W>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<W: Debug> Debug for Tr<W>

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

Formats the value using the given formatter.

impl<W: Eq> Eq for Tr<W>

impl<W: Hash> Hash for Tr<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,

impl<W: PartialEq> PartialEq<Tr<W>> for Tr<W>

fn eq(&self, other: &Tr<W>) -> bool

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

fn ne(&self, other: &Tr<W>) -> bool

This method tests for !=.

impl<W: PartialOrd> PartialOrd<Tr<W>> for Tr<W>

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

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

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

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

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

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

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

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

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

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