Struct Token 

pub struct Token {
    pub value: String,
    pub token_type: TokenType,
    pub subtype: TokenSubType,
    pub start: usize,
    pub end: usize,
}

A token in an Excel formula.

Fields

value: String

token_type: TokenType

subtype: TokenSubType

start: usize

end: usize

Implementations

impl Token

pub fn new(value: String, token_type: TokenType, subtype: TokenSubType) -> Self

pub fn new_with_span( value: String, token_type: TokenType, subtype: TokenSubType, start: usize, end: usize, ) -> Self

pub fn is_operator(&self) -> bool

pub fn get_precedence(&self) -> Option<(u8, Associativity)>

pub fn make_operand(value: String) -> Self

Create an operand token based on the value.

pub fn make_operand_with_span(value: String, start: usize, end: usize) -> Self

Create an operand token with byte position span.

pub fn make_subexp(value: &str, func: bool) -> Self

Create a subexpression token.

value must end with one of ‘{’, ‘}’, ‘(’ or ‘)’. If func is true, the token’s type is forced to be Func.

pub fn make_subexp_with_span( value: &str, func: bool, start: usize, end: usize, ) -> Self

Create a subexpression token with byte position span.

pub fn get_closer(&self) -> Result<Token, TokenizerError>

Given an opener token, return its corresponding closer token.

pub fn make_separator(value: &str) -> Self

Create a separator token.

pub fn make_separator_with_span(value: &str, start: usize, end: usize) -> Self

Create a separator token with byte position span.

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 Display for Token

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

Formats the value using the given formatter.

impl Hash for Token

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
