Struct DecimalNumber 

pub struct DecimalNumber { /* private fields */ }

Represents a decimal number.

Implementations

impl DecimalNumber

pub fn new(value: f64) -> Self

Creates a new decimal number with the given floating-point value.

pub fn with_token(self, token: Token) -> Self

Attaches a token to this decimal number.

pub fn set_token(&mut self, token: Token)

Attaches a token to this decimal number.

pub fn get_token(&self) -> Option<&Token>

Returns a reference to the token attached to this decimal number, if any.

pub fn mutate_token(&mut self) -> Option<&mut Token>

Returns a mutable reference to the token attached to this decimal number, if any.

pub fn with_exponent(self, exponent: i64, is_uppercase: bool) -> Self

Sets an exponent for this decimal number and returns the updated number.

The is_uppercase parameter determines whether the exponent uses uppercase ‘E’ or lowercase ‘e’ notation.

pub fn set_uppercase(&mut self, is_uppercase: bool)

Sets whether the exponent notation should use uppercase ‘E’ or lowercase ‘e’.

pub fn is_uppercase(&self) -> Option<bool>

Returns whether the exponent notation uses uppercase ‘E’, if an exponent is present.

pub fn get_exponent(&self) -> Option<i64>

Returns the exponent value, if one is present.

pub fn compute_value(&self) -> f64

Computes the actual numerical value represented by this decimal number.

pub fn clear_comments(&mut self)

Clears all comments from the tokens in this node.

pub fn clear_whitespaces(&mut self)

Clears all whitespaces information from the tokens in this node.

Trait Implementations

impl Clone for DecimalNumber

fn clone(&self) -> DecimalNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalNumber

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

Formats the value using the given formatter.

impl From<DecimalNumber> for Expression

fn from(number: DecimalNumber) -> Self

Converts to this type from the input type.

impl From<DecimalNumber> for NumberExpression

fn from(number: DecimalNumber) -> Self

Converts to this type from the input type.

impl PartialEq for DecimalNumber

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