Description

Linux has powerful block device mapping capabilities that are used by tools such as LVM. Froyo is a new tool that uses these capabilities in a dynamic way to create a hassle-free, redundant storage volume that grows with your data. In this talk, Froyo's creator Andy Grover will discuss its implementation, with special emphasis on the Rust language features and libraries that it builds upon.

This talk will cover a lot about libraries (serde, dbus-rs, nix, clap), how Froyo uses lang & std features (BTreeMap, Rc, RefCell, filter_map), and Froyo's internal data structures & representation.
