pub fn buffer(of view: DataView) -> array_buffer.ArrayBufferpub fn byte_length(
of view: DataView,
) -> Result(Int, js_error.JsError)The number of bytes covered by the view. Returns an error if the underlying buffer has been detached or resized below the view’s range.
pub fn byte_offset(
of view: DataView,
) -> Result(Int, js_error.JsError)The offset, in bytes, from the start of the underlying buffer. Returns an error if the underlying buffer has been detached or resized below the view’s range.

pub fn new(
buffer: array_buffer.ArrayBuffer,
