Trait Implementations

impl Clone for Value

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<StructValue> for Value

fn from(value: StructValue) -> Self

Converts to this type from the input type.

impl<T> From<Vec<T>> for Value

where T: Into<Value>,

fn from(value: Vec<T>) -> Self

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.
