Struct RcVal 

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

A newtype so the drop can be iterative: lists are unbounded in depth and derived glue overflows. On the pointer, since on Val it would forbid destructuring.

Implementations

impl RcVal

pub fn new(v: Val) -> RcVal

pub fn refs(&self) -> usize

Other threads only push the count up, so a low reading is a fact about this graph rather than a race.

pub fn unwrap_or_clone(self) -> Val

Trait Implementations

impl AsRef<Val> for RcVal

fn as_ref(&self) -> &Val

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for RcVal

fn clone(&self) -> RcVal

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RcVal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for RcVal

type Target = Val

The resulting type after dereferencing.

fn deref(&self) -> &Val

Dereferences the value.

impl Display for RcVal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for RcVal

fn drop(&mut self)

Executes the destructor for this type.

impl From<Val> for RcVal

fn from(v: Val) -> RcVal

Converts to this type from the input type.

impl PartialEq for RcVal

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