[−][src]Struct term_rewriting::Operator
A symbol with fixed arity. Only carries meaning alongside a Signature
.
To construct an Operator
, use Signature::new_op
.
Methods
impl Operator
[src]
pub fn arity(&self) -> u32
[src]
Returns an Operator
's arity.
Examples
let mut sig = Signature::default(); let op = sig.new_op(2, Some("Z".to_string())); assert_eq!(op.arity(), 2);
pub fn name(&self) -> Option<String>
[src]
Returns an Operator
's name.
Examples
let mut sig = Signature::default(); let op = sig.new_op(2, Some("Z".to_string())); assert_eq!(op.name(), Some("Z".to_string()));
pub fn display(&self) -> String
[src]
Serialize an Operator
.
Examples
let mut sig = Signature::default(); let op = sig.new_op(2, Some("Z".to_string())); assert_eq!(op.display(), "Z");
