Motivation

Description

  • Add reuseBytes option which causes deserialize to use Uint8Array#subarray instead of Uint8Array#slice. This will cause the deserialized object to share the backing ArrayBuffer of the serialized payload. This is helpful, in some cases, to avoid additional allocations, however special care must be given to avoid corrupting memory using this option. The default behavior of deserialize is unchanged.
