[−][src]Struct rusty_v8::ArrayBufferView
A base class for an instance of one of "views" over ArrayBuffer, including TypedArrays and DataView (ES6 draft 15.13).
Methods
impl ArrayBufferView
[src]
pub fn buffer<'sc>(&self) -> Option<Local<'sc, ArrayBuffer>>
[src]
Returns underlying ArrayBuffer.
pub fn byte_length(&self) -> usize
[src]
Size of a view in bytes.
pub fn byte_offset(&self) -> usize
[src]
Byte offset in |Buffer|.
pub fn copy_contents(&self, dest: &mut [u8]) -> usize
[src]
Copy the contents of the ArrayBufferView's buffer to an embedder defined memory without additional overhead that calling ArrayBufferView::Buffer might incur. Returns the number of bytes actually written.
Methods from Deref<Target = Object>
pub fn set(
&self,
context: Local<Context>,
key: Local<Value>,
value: Local<Value>
) -> MaybeBool
[src]
&self,
context: Local<Context>,
key: Local<Value>,
value: Local<Value>
) -> MaybeBool
Set only return Just(true) or Empty(), so if it should never fail, use result.Check().
pub fn create_data_property(
&self,
context: Local<Context>,
key: Local<Name>,
value: Local<Value>
) -> MaybeBool
[src]
&self,
context: Local<Context>,
key: Local<Name>,
value: Local<Value>
) -> MaybeBool
Implements CreateDataProperty (ECMA-262, 7.3.4).
Defines a configurable, writable, enumerable property with the given value on the object unless the property already exists and is not configurable or the object is not extensible.
Returns true on success.
pub fn get<'a>(
&self,
scope: &mut impl ToLocal<'a>,
context: Local<Context>,
key: Local<Value>
) -> Option<Local<'a, Value>>
[src]
&self,
scope: &mut impl ToLocal<'a>,
context: Local<Context>,
key: Local<Value>
) -> Option<Local<'a, Value>>
pub fn get_identity_hash(&self) -> int
[src]
Returns the identity hash for this object. The current implementation uses a hidden property on the object to store the identity hash.
The return value will never be 0. Also, it is not guaranteed to be unique.
