Struct Number

#[repr(C)]
pub struct Number {
    pub span: Span,
    pub value: f64,
    pub raw: Option<Atom>,
}

A numeric literal.

Creation

If you are creating a numeric literal with a dummy span, please use literal.into(), instead of creating this struct directly.

All of Box<Expr>, Expr, Lit, Number implements From<64> and From<usize>.

Fields

span: Span

value: f64

Note: This should not be NaN. Use crate::Ident to represent NaN.

If you store NaN in this field, a hash map will behave strangely.

raw: Option<Atom>

Use None value only for transformations to avoid recalculate characters in number literal

Trait Implementations

impl Archive for Number

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedNumber

The archived representation of this type.

type Resolver = NumberResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl AstNode for Number

const TYPE: &'static str = "NumericLiteral"

impl Clone for Number

fn clone(&self) -> Number

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Number

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<Number, __D> for Archived<Number>

where __D::Error: Source,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<Number, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for Number

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

Formats the value using the given formatter.

impl EqIgnoreSpan for Number

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

impl From<Number> for Box<Expr>

fn from(src: Number) -> Box<Expr>

Converts to this type from the input type.

impl From<Number> for Expr

fn from(src: Number) -> Expr

Converts to this type from the input type.

impl From<Number> for Key

fn from(src: Number) -> Key

Converts to this type from the input type.

impl From<Number> for Lit

fn from(v: Number) -> Self

Converts to this type from the input type.

impl From<Number> for PropName

fn from(v: Number) -> Self

Converts to this type from the input type.

impl From<Number> for TsLit

fn from(v: Number) -> Self

Converts to this type from the input type.

impl From<f64> for Number

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<usize> for Number

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for Number

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 Number

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

impl<__S> Serialize<__S> for Number

where __S: Writer + Allocator + Fallible + ?Sized, __S::Error: Source,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for Number

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for Number

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Eq for Number

impl StructuralPartialEq for Number
