Creates a new instance of Data with a copy of the data referred to by |data|.

This will select the type of storage based on a default threshold:

- Data up to 16KB is stored inline

- Larger data is stored in a VMO.

If data is stored in a VMO and |vmo_name| is set to a nonempty string, the VMO's

name property is set to |vmo_name|.

The cpp20::span

<const

uint8_t> overload always copies the data into the Data instance.

The std::vector

<uint8

_t> overload will reuse the existing storage if the data will

fit inline.

Returns an error if a backing store cannot be created or the name cannot be set.

Creates a new instance of Data with a copy of the data referred to by |data|

using a |size_threshold| to determine if the data should be stored inline.

If the data's size is equal or less than the threshold, it will be stored

inline. Otherwise, it will be stored in a VMO.

Returns an error if a backing store cannot be created, the name cannot be

set, or if |size_threshold| exceeds the limits of a single channel message.

Extracts the data from |data| and returns it to the caller. Consumes |data|.

Returns an error if the data instance is malformed or if the data could not

be read.
