Enum Value 

pub enum Value {
    Undefined,
    Null,
    Bool(bool),
    Num(f64),
    Str(String),
    BigInt(BigInt),
    Arr(Vec<Value>),
    Obj(Map),
    Date(i64),
    Func(u64),
}

A value under validation, or produced by it.

Variants

Undefined

No value at all: a missing property, an absent argument. JavaScript’s undefined, which JSON cannot carry.

Null

A present null.

Bool(bool)

Num(f64)

Every number is a double, as in JavaScript; NaN is a number here.

Str(String)

BigInt(BigInt)

Arr(Vec<Value>)

Obj(Map)

Date(i64)

A date, as milliseconds since the epoch, as a JavaScript Date holds it.

Func(u64)

A function value: opaque, identified so two can be told apart.

Implementations

impl Value

pub fn is_undefined(&self) -> bool

pub fn is_null(&self) -> bool

pub fn type_of(&self) -> &'static str

The typeof of the value as JavaScript reports it (undefined and null both read as “value” in messages; see value_kind).

pub fn as_obj(&self) -> Option<&Map>

pub fn as_arr(&self) -> Option<&Vec<Value>>

pub fn as_str(&self) -> Option<&str>

pub fn as_f64(&self) -> Option<f64>

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<BigInt> for Value

fn from(b: BigInt) -> Self

Converts to this type from the input type.

impl From<IndexMap<String, Value>> for Value

fn from(m: Map) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Value> for Spec

fn from(v: Value) -> Self

impl From<Value> for Value

fn from(v: Value) -> Self

Converts to this type from the input type.

impl From<Value> for Value

fn from(v: Value) -> Self

As JSON.stringify would carry it: an undefined property is dropped, an undefined element and a NaN become null, a date its ISO text.

impl From<usize> for Value

fn from(n: usize) -> Self

Converts to this type from the input type.

impl PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.
