Package digest provides a generalized type to opaquely represent message digests and their operations within the registry. The Digest type is designed to serve as a flexible identifier in a content-addressable system. More importantly, it provides tools and wrappers to work with hash.Hash-based digests with little effort. The format of a digest is simply a string with two parts, dubbed the "algorithm" and the "digest", separated by a colon: An example of a sha256 digest representation follows: The "algorithm" portion defines both the hashing algorithm used to calculate the digest and the encoding of the resulting digest, which defaults to "hex" if not otherwise specified. Currently, all supported algorithms have their digests encoded in hex strings. In the example above, the string "sha256" is the algorithm and the hex bytes are the "digest". Because the Digest type is simply a string, once a valid Digest is obtained, comparisons are cheap, quick and simple to express with the standard equality operator. The main benefit of using the Digest type is simple verification against a given digest. The Verifier interface, modeled after the stdlib hash.Hash interface, provides a common write sink for digest verification. After writing is complete, calling the Verifier.Verified method will indicate whether or not the stream of bytes matches the target digest. In addition to the above, we intend to add the following features to this package: 1. A Digester type that supports write sink digest calculation. 2. Suspend and resume of ongoing digest calculations to support efficient digest verification in the registry.

Package apbf implements an optimized Age-Partitioned Bloom Filter. This example demonstrates creating a new APBF, adding items to it up to the maximum capacity, querying the oldest item, then adding more items to it in order to cause the older items to be evicted.

Package container is a lightweight yet powerful IoC container for Go projects. It provides an easy-to-use interface and performance-in-mind container to be your ultimate requirement.

Package btrfs provides bindings for working with btrfs partitions from Go.

Package image provides libraries and commands to interact with containers images. TODO(runcom)

Package container provides an IoC container for Go projects. It provides simple, fluent and easy-to-use interface to make dependency injection in GoLang easier.

Package psgo is a ps (1) AIX-format compatible golang library extended with various descriptors useful for displaying container-related data. The idea behind the library is to provide an easy to use way of extracting process-related data, just as ps (1) does. The problem when using ps (1) is that the ps format strings split columns with whitespaces, making the output nearly impossible to parse. It also adds some jitter as we have to fork and execute ps either in the container or filter the output afterwards, further limiting applicability. Please visit https://github.com/containers/psgo for further details about supported format descriptors and to see some usage examples.
