[−][src]Struct rusty_v8::BackingStore
A wrapper around the backing store (i.e. the raw memory) of an array buffer. See a document linked in http://crbug.com/v8/9908 for more information.
The allocation and destruction of backing stores is generally managed by V8. Clients should always use standard C++ memory ownership types (i.e. std::unique_ptr and std::shared_ptr) to manage lifetimes of backing stores properly, since V8 internal objects may alias backing stores.
This object does not keep the underlying |ArrayBuffer::Allocator| alive by default. Use Isolate::CreateParams::array_buffer_allocator_shared when creating the Isolate to make it hold a reference to the allocator itself.
Methods
impl BackingStore
[src]
pub fn data_bytes<'a>(&'a mut self) -> &'a mut [u8]
[src]
Returns a rust u8 slice with a lifetime equal to the lifetime of the BackingStore.
pub fn data(&mut self) -> &mut c_void
[src]
Return a pointer to the beginning of the memory block for this backing store. The pointer is only valid as long as this backing store object lives.
pub fn byte_length(&self) -> usize
[src]
The length (in bytes) of this backing store.
pub fn is_shared(&self) -> bool
[src]
Indicates whether the backing store was created for an ArrayBuffer or a SharedArrayBuffer.
