[−][src]Struct rusty_v8::ArrayBuffer
An instance of the built-in ArrayBuffer constructor (ES6 draft 15.13.5).
Methods
impl ArrayBuffer
[src]
pub fn new<'sc>(
scope: &mut impl ToLocal<'sc>,
byte_length: usize
) -> Local<'sc, ArrayBuffer>
[src]
scope: &mut impl ToLocal<'sc>,
byte_length: usize
) -> Local<'sc, ArrayBuffer>
Create a new ArrayBuffer. Allocate |byte_length| bytes. Allocated memory will be owned by a created ArrayBuffer and will be deallocated when it is garbage-collected, unless the object is externalized.
pub fn new_with_backing_store<'sc>(
scope: &mut impl ToLocal<'sc>,
backing_store: &mut SharedRef<BackingStore>
) -> Local<'sc, ArrayBuffer>
[src]
scope: &mut impl ToLocal<'sc>,
backing_store: &mut SharedRef<BackingStore>
) -> Local<'sc, ArrayBuffer>
pub fn byte_length(&self) -> usize
[src]
Data length in bytes.
pub fn get_backing_store(&self) -> SharedRef<BackingStore>
[src]
pub fn new_backing_store(
scope: &mut impl InIsolate,
byte_length: usize
) -> UniqueRef<BackingStore>
[src]
scope: &mut impl InIsolate,
byte_length: usize
) -> UniqueRef<BackingStore>
Returns a new standalone BackingStore that is allocated using the array buffer allocator of the isolate. The result can be later passed to ArrayBuffer::New.
If the allocator returns nullptr, then the function may cause GCs in the given isolate and re-try the allocation. If GCs do not help, then the function will crash with an out-of-memory error.
