Struct rusty_v8::Private

#[repr(C)]
pub struct Private(_);

A private symbol

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

Implementations

impl Private

pub fn new<'s>(
    scope: &mut HandleScope<'s, ()>,
    name: Option<Local<'_, String>>
) -> Local<'s, Private>

Create a private symbol. If name is not empty, it will be the description.

pub fn for_api<'s>(
    scope: &mut HandleScope<'s, ()>,
    name: Option<Local<'_, String>>
) -> Local<'s, 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”.

pub fn name<'s>(&self, scope: &mut HandleScope<'s, ()>) -> Local<'s, Value>

Returns the print name string of the private symbol, or undefined if none.

Methods from Deref<Target = Data>

pub fn get_hash(&self) -> int

Returns the V8 hash value for this value. The current implementation uses a hidden property to store the identity hash on some object types.

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

pub fn is_value(&self) -> bool

Returns true if this data is a Value.

pub fn is_module(&self) -> bool

Returns true if this data is a Module.

pub fn is_private(&self) -> bool

Returns true if this data is a Private.

pub fn is_object_template(&self) -> bool

Returns true if this data is an ObjectTemplate

pub fn is_function_template(&self) -> bool

Returns true if this data is a FunctionTemplate.

Trait Implementations

impl Debug for Private

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

Formats the value using the given formatter.

impl Deref for Private

type Target = Data

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for Private

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, 

Feeds a slice of this type into the given Hasher.

impl<'s> PartialEq<Data> for Private

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'s> PartialEq<Private> for Data

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'s> PartialEq<Private> for Private

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
