GuestBytes

value class GuestBytes(value: PolyglotValue)

A light wrapper around a guest buffer-like value, providing indexed access. This helper can be used to wrap the ArrayBuffer instances backing a Uint8Array or similar, for convenience when manipulating them.

Note that no validation of any kind is performed during construction or by any of the operators.
