Struct conllx::Features

pub struct Features { /* fields omitted */ }

Token features.

In the CoNLL-X specification, these are morphological features of the token. Typically, the features are a list or a key-value mapping.

Methods

impl Features

fn from_string<S>(s: S) -> Self where
    S: Into<String>, 

Create features from a string. The casual format uses key-value pairs that are separated by a vertical bar (|) and keys and values using a colon (:). Arbitrary strings will also be accepted, however they will not give a nice feature-value mapping when using as_map.

fn as_map(&self) -> &BTreeMap<String, Option<String>>

Get the features field as a key-value mapping. This assumes that the key-value pairs are separed using a vertical bar (|) and keys and values using a colon (:). If the value is absent, corresponding value in the mapping is None.

The feature map is constructed lazily:

• If as_map is never called, the feature map is never created.
• If as_map is called once or more, the feature map is only created once.

fn as_str(&self) -> &str

Get the features field.
