alt Hacker News> Zero-copy deserialization. uv uses rkyv to deserialize cached data without copying it. The data format is the in-memory format. This is a Rust-specific technique.
This (zero-copy deserialization) is not a rust-specific technique, so I'm not entirely sure why the author describes it as one. Any good low level language (C/C++ included) can do this from my experience.

I think the framing in the post is that it's specific to Rust, relative to what Python packaging tools are otherwise written in (Python). It's not very easy to do zero-copy deserialization in pure Python, from experience.
(But also, I think Rust can fairly claim that it's made zero-copy deserialization a lot easier and safer.)
It's Rust vs Python in this case.
They speak about “technique” but rkyv is a Rust-specific format. Could be an editing error or maybe they’re suggesting it’s more difficult in python.
Given the context of the article, I think "Rust specific" here means that "it couldn't be done in python".
For example "No interpreter startup" is not specific to Rust either.
