Methods

impl Token

pub fn new(word: &str, quote_style: Option<char>) -> Self

Creates a new token. quote style is None for integers.

pub fn get_value(&self) -> String

Gets the value of the column encoded in an string. For numbers use get_number

pub fn get_number(&self) -> Option<f64>

If the token contains a number and it can be parsed, returns Some(number). None if not.

pub fn is_keyword(&self) -> bool

returns if the Token contains a keyword

pub fn get_quote_style(&self) -> Option<char>

gets the quote style. None if none or it doesn't apply

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy 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 Display for Token

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

Formats the value using the given formatter.

impl From<Token> for String

fn from(token: Token) -> String

Performs the conversion.

impl PartialEq<Token> for Token

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Token) -> bool

This method tests for !=.
