Struct rusty_v8_m::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>
) -> Option<bool>

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

pub fn set_index(
    &self,
    context: Local<Context>,
    index: u32,
    value: Local<Value>
) -> Option<bool>

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

pub fn get_property_names<'a>(
    &self,
    scope: &mut impl ToLocal<'a>,
    context: Local<Context>
) -> Local<'a, Array>

pub fn set_prototype(
    &self,
    context: Local<Context>,
    prototype: Local<Value>
) -> Option<bool>

Set the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

pub fn create_data_property(
    &self,
    context: Local<Context>,
    key: Local<Name>,
    value: Local<Value>
) -> Option<bool>

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 define_own_property(
    &self,
    context: Local<Context>,
    key: Local<Name>,
    value: Local<Value>,
    attr: PropertyAttribute
) -> Option<bool>

Implements DefineOwnProperty.

In general, CreateDataProperty will be faster, however, does not allow for specifying attributes.

Returns true on success.

pub fn get<'a>(
    &self,
    scope: &mut impl ToLocal<'a>,
    context: Local<Context>,
    key: Local<Value>
) -> Option<Local<'a, Value>>

pub fn get_index<'a>(
    &self,
    scope: &mut impl ToLocal<'a>,
    context: Local<Context>,
    index: u32
) -> Option<Local<'a, Value>>

pub fn get_prototype<'a>(
    &self,
    scope: &mut impl ToLocal<'a>
) -> Option<Local<'a, Value>>

Get the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

pub fn get_identity_hash(&self) -> int

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.

pub fn creation_context<'a>(
    &self,
    scope: &mut impl ToLocal<'a>
) -> Local<'a, Context>

Returns the context in which the object was created.

impl Deref for ArrayBufferView

type Target = Object

The resulting type after dereferencing.

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

Dereferences the value.
