Nonterminal Node.
Terminal(Terminal)
Terminal Node.
Methods
impl Node
[src]
pub fn is_terminal(&self) -> bool
[src]
Returns whether a self
is Terminal
.
pub fn terminal(&self) -> Option<&Terminal>
[src]
Get a Option<&Terminal>
.
Returns None
if self
is a Node::NonTerminal
.
pub fn nonterminal(&self) -> Option<&NonTerminal>
[src]
Get a Option<&NonTerminal>
.
Returns None
if self
is a Node::Terminal
.
pub fn nonterminal_mut(&mut self) -> Option<&mut NonTerminal>
[src]
Get a Option<&mut NonTerminal>
.
Returns None
if self
is a Node::Terminal
.
pub fn continuity(&self) -> Continuity
[src]
Returns whether this node's span is continuous.
This does not return whether this node introduces a edge cutting another node's span. It does return whether this node's span is continuous.
pub fn terminal_mut(&mut self) -> Option<&mut Terminal>
[src]
Get a Option<&mut Terminal>
.
Returns None
if self
is a Node::NonTerminal
.
pub fn label(&self) -> &str
[src]
Get the node's label.
Returns the part-of-speech for Terminal
s and the node label for NonTerminal
s.
pub fn set_label(&mut self, s: impl Into<String>) -> String
[src]
Set the node's label.
Returns the replaced label.
pub fn features(&self) -> Option<&Features>
[src]
Get this Node
's Features
.
pub fn features_mut(&mut self) -> &mut Features
[src]
Get this Node
's Features
mutably.
This method initializes the features if they are None
.
pub fn set_features(&mut self, features: Option<Features>) -> Option<Features>
[src]
Set this NonTerminal
's Features
.
Returns the replaced value.
pub fn span(&self) -> &Span
[src]
Get a Node
's span.
