TODO a mix between runtime numbers and source syntax based number TODO hex cases lost in input :( https://tc39.es/ecma262/multipage/ecmascript-language-lexical-grammar.html#sec-literals-numeric-literals

Some of these can’t be parsed, but are there to make is so that a number can be generated from just a f64

Implementations

impl NumberRepresentation

pub fn as_js_string(self) -> String

Trait Implementations

impl Clone for NumberRepresentation

fn clone(&self) -> NumberRepresentation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumberRepresentation

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

Formats the value using the given formatter.

impl Display for NumberRepresentation

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

Formats the value using the given formatter.

impl From<f64> for NumberRepresentation

fn from(value: f64) -> Self

Converts to this type from the input type.

impl FromStr for NumberRepresentation

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for NumberRepresentation

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 NumberRepresentation

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SelfRustTokenize for NumberRepresentation

fn append_to_token_stream(&self, token_stream: &mut TokenStream)

fn to_tokens(&self) -> TokenStream

Returns the tokens used to construct self

impl Serialize for NumberRepresentation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<NumberRepresentation> for f64

type Error = ()

The type returned in the event of a conversion error.

fn try_from(this: NumberRepresentation) -> Result<Self, Self::Error>

Performs the conversion.

impl Visitable for NumberRepresentation

fn visit<TData>( &self, _visitors: &mut (impl VisitorReceiver<TData> + ?Sized), _data: &mut TData, _options: &VisitOptions, _chain: &mut Annex<'_, Chain> )

fn visit_mut<TData>( &mut self, _visitors: &mut (impl VisitorMutReceiver<TData> + ?Sized), _data: &mut TData, _options: &VisitOptions, _chain: &mut Annex<'_, Chain> )
