Enum Token 

pub enum Token {
    Ident(String),
    Number(String),
    String(String),
    OpenParen,
    CloseParen,
    Comma,
    Operator(String),
}

A lexical token consumed by the precedence parser.

Variants

Ident(String)

An identifier token carrying its text.

Number(String)

A numeric literal token carrying its source text.

String(String)

A string literal token carrying its contents.

OpenParen

An opening parenthesis.

CloseParen

A closing parenthesis.

Comma

An argument separator comma.

Operator(String)

An operator token carrying its symbol text.

Implementations

impl Token

pub fn symbol_text(&self) -> Option<&str>

Returns the symbol text for operator and identifier tokens, or None for tokens that carry no operator-table key.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl Eq for Token

impl PartialEq for Token

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