The purpose of the library is providing an interface for managing git-dit issues, associated messages and metadata. Naturally, this is done via types representing different aspects which are grouped in modules.

• repository provides the RepositoryExt extension trait, which is the main facade through which users may create, find and access issues.

• issue provides the Issue type which represents an issue and provides interfaces for creating and accessing the issue's messages.

• message provides the Message trait as well as line- and block-oriented iterators for processing a single git-dit message.

• trailer provides the Trailer type for representing trailers as well as interfaces for specifying, accumulating and matching trailers.

• gc provides utilities which may be used for garbage collection in git-dit environment.

• iter provides various iterators for stream-processing, most notably the Messages iterator.

• error provides all error types for the library.

• utils provides strictly library internal utilities, which will never be exported.

• test_utils provides library internal testing utilities.

We impose a number of restrictions on inter-module dependencies.

• utils, test_utils and error shall not depend on any other module of the library.

• Generally, sub-modules shall not depend on siblings of its super-module. For example, trailers::accumulation shall not depend on repository. The aforementioned utils, test_utils error modules are excepted from this rule. Any module or submodule may depend on them.

• However, the message module and associated sub-modules may depend on trailer and its submodules.
