Struct v8::value::Private

pub struct Private(_, _);

A private symbol

This is an experimental feature. Use at your own risk.

Methods

impl Private

fn new(isolate: &Isolate, name: &String) -> Private

Create a private symbol.

If name is not empty, it will be the description.

fn for_api_name(isolate: &Isolate, name: &String) -> Private

Retrieve a global private symbol.

If a symbol with this name has not been retrieved in the same isolate before, it is created. Note that private symbols created this way are never collected, so they should only be used for statically fixed properties. Also, there is only one global name space for the names used as keys. To minimize the potential for clashes, use qualified names as keys, e.g., "Class#property".

unsafe fn from_raw(isolate: &Isolate, raw: PrivateRef) -> Private

Creates a private from a set of raw pointers.

fn as_raw(&self) -> PrivateRef

Returns the underlying raw pointer behind this private.

Methods from Deref<Target=Name>

fn get_identity_hash(&self) -> u32

Returns the identity hash for this object.

The current implementation uses an inline property on the object to store the identity hash.

The return value will never be 0. Also, it is not guaranteed to be unique.

fn as_raw(&self) -> NameRef

Returns the underlying raw pointer behind this primitive.

Trait Implementations

impl Debug for Private

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Deref for Private

type Target = Name

The resulting type after dereferencing

fn deref(&self) -> &Self::Target

The method called to dereference a value

impl Clone for Private

fn clone(&self) -> Private

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Drop for Private

fn drop(&mut self)

A method called when the value goes out of scope.
