Struct rusty_v8::ArrayBufferView

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

A base class for an instance of one of "views" over ArrayBuffer, including TypedArrays and DataView (ES6 draft 15.13).

Methods

impl ArrayBufferView

pub fn buffer<'sc>(&self) -> Option<Local<'sc, ArrayBuffer>>

Returns underlying ArrayBuffer.

pub fn byte_length(&self) -> usize

Size of a view in bytes.

pub fn byte_offset(&self) -> usize

Byte offset in |Buffer|.

pub fn copy_contents(&self, dest: &mut [u8]) -> usize

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

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

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>>

Trait Implementations

impl Deref for ArrayBufferView

type Target = Object

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
