Enum Value 

pub enum Value {
    Null,
    String(String),
    Number(f64),
    Boolean(bool),
    Array(Vec<Value>),
    Object(HashMap<String, Value>),
}

A runtime value in the Patchwork language.

Variants

Null

The null value.

String(String)

A string value.

Number(f64)

A numeric value (always f64, like JavaScript).

Boolean(bool)

A boolean value.

Array(Vec<Value>)

An array of values.

Object(HashMap<String, Value>)

An object with string keys.

Implementations

impl Value

pub fn to_string_value(&self) -> String

Coerce this value to a string.

pub fn to_bool(&self) -> bool

Coerce this value to a boolean.

pub fn is_null(&self) -> bool

Check if this value is null.

pub fn from_json(s: &str) -> Result<Value, String>

Parse a JSON string into a Value.

pub fn to_json(&self) -> String

Convert this Value to a JSON string.

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() -> Self

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 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.
