Struct Terminal

pub struct Terminal { /* private fields */ }

Struct representing a Terminal.

Terminals are represented by:

• form - word form
• pos - part of speech tag
• lemma - (optional) lemma
• morph - (optional) morphological features
• span - position in the sentence

Implementations

impl Terminal

pub fn new(form: impl Into<String>, pos: impl Into<String>, idx: usize) -> Self

Construct new Terminal.

Constructs a new Terminal with the given form and part-of-speech tag at the specified index.

pub fn span(&self) -> &Span

Returns the Terminal’s span.

A Terminal’s span is defined as a tuple (n, n+1) where n is the 0-based position of the Terminal in the sentence.

pub fn idx(&self) -> usize

Returns the Terminal’s linear position in the sentence.

pub fn form(&self) -> &str

Return the Terminals form.

pub fn set_form(&mut self, new_form: impl Into<String>) -> String

Replace form with new_form. Return old value.

pub fn label(&self) -> &str

Return part of speech.

pub fn set_label(&mut self, new_pos: impl Into<String>) -> String

Replace part of speech with new_pos. Return old value.

pub fn features(&self) -> Option<&Features>

Get this Terminal’s Features.

pub fn features_mut(&mut self) -> &mut Features

Get this Terminal’s Features mutably.

This method initializes the features if they are None.

pub fn set_features(&mut self, features: Option<Features>) -> Option<Features>

Set this Terminal’s Features.

Returns the replaced value.

pub fn lemma(&self) -> Option<&str>

Return lemma if present, else None.

pub fn set_lemma<S>(&mut self, new_lemma: Option<S>) -> Option<String>

where S: Into<String>,

Replace lemma with new_lemma. Return old value.

Trait Implementations

impl Clone for Terminal

fn clone(&self) -> Terminal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Terminal

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

Formats the value using the given formatter.

impl Display for Terminal

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

Formats the value using the given formatter.

impl<'a> From<&'a Terminal> for Token

fn from(terminal: &Terminal) -> Self

Converts to this type from the input type.

impl From<Terminal> for Node

fn from(t: Terminal) -> Self

Converts to this type from the input type.

impl PartialEq for Terminal

fn eq(&self, other: &Terminal) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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