Crate 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

Structs

TryFromJsValueError	Returned when attempting to convert a JsValue to a TypedArray.
TryFromTypedArrayError	Returned when attempting to convert a TypedArray to a specific typed array instance.

Enums

TypedArray

An enum of all of the typed arrays that is available in Javascipt. Common functionality is implemented on this type to make handling all variants easier.
