Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

pub 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<(), Error>

Formats the value using the given formatter.

impl From<Builtin> for Value

fn from(bt: Builtin) -> Self

Performs the conversion.

impl From<Vec<Value, Global>> for Value

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

Performs the conversion.

impl IntoIterator for Value

type Item = Value

The type of the elements being iterated over.

type IntoIter = ValueIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq<Value> for Value

fn eq(&self, other: &Value) -> bool
