pub struct ArrayBuffer { /* fields omitted */ }
The ArrayBuffer
object is used to represent a generic,
fixed-length raw binary data buffer. You cannot directly
manipulate the contents of an ArrayBuffer
; instead, you
create one of the typed array objects or a DataView
object
which represents the buffer in a specific format, and use that
to read and write the contents of the buffer.
MDN documentation
The byteLength property of an object which is an instance of type ArrayBuffer
it's an accessor property whose set accessor function is undefined,
meaning that you can only read this property.
The value is established when the array is constructed and cannot be changed.
This property returns 0 if this ArrayBuffer has been detached.
MDN documentation
The isView()
method returns true if arg is one of the ArrayBuffer
views, such as typed array objects or a DataView; false otherwise.
MDN documentation
The slice()
method returns a new ArrayBuffer
whose contents
are a copy of this ArrayBuffer
's bytes from begin, inclusive,
up to end, exclusive.
MDN documentation
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
MDN documentation
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
MDN documentation
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
MDN documentation
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
MDN documentation
The valueOf()
method returns the primitive value of the
specified object.
