zerocopy with Joshua Liebow-Feeser
Shownotes
Episode 10 – zerocopy with Joshua Liebow-Feeser.
A conversation with Joshua Liebow-Feeser, the developer behind netstack3 and the creator of zerocopy, a crate that makes zero-cost memory manipulation effortless. Originally built for Fuchsia, zerocopy is now used by over 400 crates on crates.io, with nearly 300 million downloads.
We explore the origins of Fuchsia, the creation and purpose of zerocopy, how it works, and why you might want to use it. And of course, we get to know Joshua and his journey so far.
