Struct Value 

pub struct Value(/* private fields */);

The universal runtime handle for every object.

A Value is a reference-counted handle to a RuntimeObject; it is the object end of the data flow tokens -> checked forms -> objects -> checked calls -> objects -> encoded forms. Equality and hashing are by object identity (pointer), not by structural contents.

Examples

// Every value exposes its object and that object's header.
let header = value.header();
let _same = value.object().header();
let _ = header;

Implementations

impl Value

pub fn object(&self) -> &(dyn RuntimeObject + 'static)

Borrows the underlying runtime object.

pub fn header(&self) -> &ObjectHeader

Borrows the object’s ObjectHeader.

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 Eq for Value

impl Hash for Value

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Value

fn eq(&self, other: &Self) -> 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.
