Crate ostree_ext 

Extension APIs for ostree

This crate builds on top of the core ostree C library and the Rust bindings to it, adding new functionality written in Rust.

Key Modules

• container: Bidirectional mapping between OCI container images and ostree commits. This is the core of bootc’s ability to deploy container images as bootable systems.
• tar: Lossless export and import of ostree commits as tar archives.
• sysroot: Extensions for managing ostree deployments.
• chunking: Splitting ostree commits into layers for efficient container updates.
