Struct rusty_v8::ArrayBuffer

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

An instance of the built-in ArrayBuffer constructor (ES6 draft 15.13.5).

Methods

impl ArrayBuffer

pub fn new<'sc>(
    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>

pub fn byte_length(&self) -> usize

Data length in bytes.

pub fn get_backing_store(&self) -> SharedRef<BackingStore>

pub fn new_backing_store(
    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.
