Implementations

impl Value

pub fn describe(&self) -> ValueDescription<'_>

Returns a formattable that gives a helper description of the value.

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

Returns the string if this value is a string, otherwise None.

pub fn into_string(self) -> Option<String>

Returns the string if this value is a string, otherwise None.

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

Returns a f64 if the value can be converted to it, otherwise None.

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<'de> Deserialize<'de> for Value

fn deserialize<D>(deserializer: D) -> Result<Value, D::Error>

Deserialize this value from the given Serde deserializer.

impl Empty for Value

fn is_empty(&self) -> bool

Returns whether this value is empty.

fn is_deep_empty(&self) -> bool

Returns whether this value is empty or all of its descendants are empty.

impl<'a> From<&'a Value> for Val<'a>

fn from(value: &'a Value) -> Self

Converts to this type from the input type.

impl<'a> From<&'a str> for Value

fn from(value: &'a str) -> Self

Converts to this type from the input type.

fn from(value: Object<Value>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Value> for Value

fn from(value: Value) -> Value

Converts to this type from the input type.

impl From<Vec<Annotated<Value>>> for Value

fn from(value: Array<Value>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(value: u64) -> Self

Converts to this type from the input type.

impl FromValue for Value

fn from_value(value: Annotated<Value>) -> Annotated<Value>

Creates a meta structure from an annotated boxed value.

impl IntoValue for Value

fn into_value(self) -> Value

Boxes the meta structure back into a value.

fn serialize_payload<S>( &self, s: S, _behavior: SkipSerialization, ) -> Result<S::Ok, S::Error>

where Self: Sized, S: Serializer,

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
