String(String)

Array(Vec<Value>)

Object(HashMap<String, Value>)

Implementations

impl Value

pub fn is_truthy(&self) -> bool

false, null, 0, 0.0, and "" are falsy. Everything else (including empty arrays []) is truthy.

pub fn is_null(&self) -> bool

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

pub fn to_display_string(&self) -> String

Returns the display string for this value (used in interpolation).

pub fn to_json_string(&self) -> String

Serialises the value as a JSON string.

pub fn html_escaped(&self) -> String

Returns the HTML-escaped display string (safe for insertion into HTML).

pub fn length(&self) -> Option<usize>

pub fn is_empty(&self) -> bool

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 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<HashMap<String, Value>> for Value

fn from(m: HashMap<String, Value>) -> 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<Vec<Value>> for Value

fn from(v: Vec<Value>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(i: i64) -> Self

Converts to this type from the input type.

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.
