[−][src]Struct rusty_v8::SharedArrayBuffer
An instance of the built-in SharedArrayBuffer constructor. This API is experimental and may change significantly.
Methods
impl SharedArrayBuffer
[src]
pub fn new<'sc>(
scope: &mut impl ToLocal<'sc>,
byte_length: usize
) -> Option<Local<'sc, SharedArrayBuffer>>
[src]
scope: &mut impl ToLocal<'sc>,
byte_length: usize
) -> Option<Local<'sc, SharedArrayBuffer>>
Create a new SharedArrayBuffer. Allocate |byte_length| bytes. Allocated memory will be owned by a created SharedArrayBuffer and will be deallocated when it is garbage-collected, unless the object is externalized.
pub fn byte_length(&self) -> usize
[src]
Data length in bytes.
pub fn get_backing_store(&self) -> SharedRef<BackingStore>
[src]
Get a shared pointer to the backing store of this array buffer. This pointer coordinates the lifetime management of the internal storage with any live ArrayBuffers on the heap, even across isolates. The embedder should not attempt to manage lifetime of the storage through other means.
Methods from Deref<Target = Value>
pub fn is_undefined(&self) -> bool
[src]
Returns true if this value is the undefined value. See ECMA-262 4.3.10.
pub fn is_null(&self) -> bool
[src]
Returns true if this value is the null value. See ECMA-262 4.3.11.
pub fn is_null_or_undefined(&self) -> bool
[src]
Returns true if this value is either the null or the undefined value. See ECMA-262 4.3.11. and 4.3.12
pub fn is_string(&self) -> bool
[src]
Returns true if this value is an instance of the String type. See ECMA-262 8.4.
pub fn is_array(&self) -> bool
[src]
Returns true if this value is an array. Note that it will return false for an Proxy for an array.
pub fn is_function(&self) -> bool
[src]
Returns true if this value is a function.
pub fn is_object(&self) -> bool
[src]
Returns true if this value is an object.
pub fn is_number(&self) -> bool
[src]
Returns true if this value is a number.
pub fn strict_equals<'sc>(&self, that: Local<'sc, Value>) -> bool
[src]
pub fn same_value<'sc>(&self, that: Local<'sc, Value>) -> bool
[src]
