Enum TokenKind 

pub enum TokenKind {
    LParen,
    RParen,
    Symbol(String),
    Keyword(String),
    Variable(String),
    Number(f64),
}

The kind of a lexed PDDL token.

Variants

LParen

Opening parenthesis (.

RParen

Closing parenthesis ).

Symbol(String)

An identifier: predicate names, type names, operators (+, -, …), etc. Stored in lowercase.

Keyword(String)

A PDDL keyword starting with : (e.g. :requirements, :typing). The leading : is stripped; stored in lowercase.

Variable(String)

A PDDL variable starting with ? (e.g. ?x, ?duration). The leading ? is kept; stored in lowercase.

Number(f64)

An integer or floating-point numeric literal.

Trait Implementations

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenKind

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

Formats the value using the given formatter.

impl PartialEq for TokenKind

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