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<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for Value

fn from(v: &str) -> Self

Converts to this type from the input type.

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

fn from(v: HashMap<String, Value>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(v: 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(v: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

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.

where S: Serializer,

Serialize this value into the given Serde serializer.
