Struct rusty_v8::Private [−][src]
A private symbol
This is an experimental feature. Use at your own risk.
Implementations
impl Private
[src]
pub fn new<'s>(
scope: &mut HandleScope<'s, ()>,
name: Option<Local<'_, String>>
) -> Local<'s, Private>
[src]
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>
[src]
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>
[src]
Returns the print name string of the private symbol, or undefined if none.
Methods from Deref<Target = Data>
pub fn get_hash(&self) -> int
[src]
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
[src]
Returns true if this data is a Value
.
pub fn is_module(&self) -> bool
[src]
Returns true if this data is a Module
.
pub fn is_private(&self) -> bool
[src]
Returns true if this data is a Private
.
pub fn is_object_template(&self) -> bool
[src]
Returns true if this data is an ObjectTemplate
pub fn is_function_template(&self) -> bool
[src]
Returns true if this data is a FunctionTemplate.
