If you build this library with the default
alloc feature disabled then while
the non-macro form of the testaments are offered, they cannot be rendered
and the render_testament macro will not be provided.
In both render_testament and git_testament_macros you will find mention of the concept of a “trusted” branch. This exists as a way to allow releases to be made from branches which are not yet tagged. For example, if your release process requires that the release binaries be built and tested before tagging the repository then by nominating a particular branch as trusted, you can cause the rendered testament to trust the crate’s version rather than being quite noisy about how the crate version and the tag version do not match up.
