    Null,
    Bool(bool),
    Number(f64),
    String(String),
    Array(Vec<Value>),
    Object(HashMap<String, Value>),

Variants

Null

Represents a Null value.

Bool(bool)

Represents a Boolean.

Represents a floating point Number.

String(String)

Represents a String.

Array(Vec<Value>)

Represents an Array of script values.

Object(HashMap<String, Value>)

Represents an Object of script values.

Implementations

impl Value

pub fn is_null(&self) -> bool

Returns true if the Value is a Null. Returns false otherwise.

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

If the Value is a Boolean, returns the associated bool. Returns [None] otherwise.

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

If the Value is a String, returns the associated str. Returns None` otherwise.

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

If the Value is a Number, returns the associated f64. Returns None` otherwise.

pub fn as_slice(&self) -> Option<&[Value]>

If the Value is an Array, returns the associated slice. Returns None` otherwise.

pub fn as_object(&self) -> Option<&HashMap<String, Value>>

If the Value is an Object, returns the associated HashMap. Returns None` otherwise.

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<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Value> for Value

fn from(value: JsonValue) -> Self

Converts to this type from the input type.

impl From<Value> for Value

fn from(value: Value) -> Self

Converts to this type from the input type.

impl<'a, K: IntoValue> FromIterator<(&'a str, K)> for Value

fn from_iter<T: IntoIterator<Item = (&'a str, K)>>(iter: T) -> Self

Creates a value from an iterator.

impl<K: IntoValue> FromIterator<(String, K)> for Value

fn from_iter<T: IntoIterator<Item = (String, K)>>(iter: T) -> Self

Creates a value from an iterator.

impl<K: IntoValue> FromIterator<K> for Value

fn from_iter<T: IntoIterator<Item = K>>(iter: T) -> Self

Creates a value from an iterator.

impl IntoValue for Value

fn into_value(self) -> Value

Converts this type into the related Value variant.

impl PartialEq for Value

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&Value> for Value

type Error = EvaluationError

The type returned in the event of a conversion error.

fn try_from(value: &PelValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFromValue for Value

fn try_from_value(value: Value) -> Result<Self, EvaluationError>

Performs the conversion.
