Enum Number 

#[non_exhaustive]
pub enum Number {
    Integer(i128),
    Float(f64),
}

Simpler representation of numbers so operations are simpler to handle Also can be used for custom filters/tests/fn when you want to ensure you get a number

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Integer(i128)

Integers are stored in i128, which means we can’t use numbers from u128 above i128::MAX for math, which is probably ok for a template engine.

Float(f64)

Implementations

impl Number

pub fn is_float(&self) -> bool

Is the number a float?

pub fn is_integer(&self) -> bool

Is the number an integer? Does not check whether the float could be converted to an integer losslessly, just checks the type.

pub fn as_float(&self) -> f64

Converts a number to a float.

pub fn as_integer(&self) -> Option<i128>

Tries to convert a number to a i128.

Trait Implementations

impl<'k> ArgFromValue<'k> for Number

type Output = Number

fn from_value( value: &'k Value, ) -> Result<<Number as ArgFromValue<'k>>::Output, Error>

impl Clone for Number

fn clone(&self) -> Number

Returns a duplicate of the value.

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

impl Copy for Number

impl Debug for Number

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

Formats the value using the given formatter.

impl Display for Number

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

impl From<Number> for Value

fn from(n: Number) -> Value

Converts to this type from the input type.

impl PartialEq for Number

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Number

fn partial_cmp(&self, other: &Number) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
