Struct Rule 

pub struct Rule {
    pub id: i32,
    pub inputs: Vec<Vec<Token>>,
    pub outputs: Vec<Vec<Token>>,
    pub source_span: LineColSpan,
    /* private fields */
}

Represents a Throne rule.

A Rule is uniquely identified by its id. Each input and output for a Rule is a Phrase.

Fields

id: i32

inputs: Vec<Vec<Token>>

outputs: Vec<Vec<Token>>

source_span: LineColSpan

Implementations

impl Rule

pub fn to_string(&self, string_cache: &StringCache) -> String

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> 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.
