Struct lumberjack::Features

pub struct Features { /* fields omitted */ }

Features.

These can be e.g. morphological features on Terminal or syntactic-semantic labels on NonTerminal nodes.

Methods

impl Features

pub fn new() -> Self

Construct empty Features.

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

Get a slice of the backing BTreeMap.

pub fn inner_mut(&mut self) -> &mut BTreeMap<String, Option<String>>

Get the backing BTreeMap mutably.

pub fn insert<K, V>(&mut self, key: K, val: Option<V>) -> Option<String> where
    K: Into<String>,
    V: Into<String>, 

Insert key with val.

If key was present, the replaced value is returned, otherwise None.

pub fn get_val(&self, key: &str) -> Option<&str>

Get the value associated with key.

pub fn remove(&mut self, key: &str) -> Option<String>

Remove the tuple associated with key.

Returns None if key was not found.
