typed-array

A wrapper for all typed array types from js_sys that implements common functionality and useful conversions.

All typed arrays in Javascript have properties like buffer, subarray and byte_length in common. However, they can be tricky to work with if the variant is not known. This wrapper type makes it easy to use all typed arrays in the way you'd expect.

Examples

use typed_array::TypedArray;
use js_sys::Uint8Array;

fn length_of_typed_array<T: Into<TypedArray>>(typed_array: T) -> u32 {
    typed_array.into().length()
}

assert_eq!(
    length_of_typed_array(Uint8Array::new(&10.into())),
    10
);

Features

The following common functionality between typed arrays is implemented:

• buffer
• subarray
• slice
• length
• byte_length
• byte_offset
• set

Additionally, conversions are easy:

• From<X> for TypedArray
• TryFrom<TypedArray> for X
• TryFrom<JsValue> for TypedArray
• AsRef<JsValue> for TypedArray
• AsRef<Object> for TypedArray
• has_type, analogous to JsCast::has_type
• dyn_into, analogous to JsCast::dyn_into
