or: "Know Your Dependencies"
One of Abscissa's primary goals is to maximize functionality while minimizing the number of dependencies. Abscissa is used in a number of high-security contexts, and as such we view each additional dependency as additional attack surface and therefore a potential liability. We have therefore been very conscientious about the dependencies we use and will not add additional dependencies without due consideration.
Here are all of Abscissa's transitive dependencies when configured with the default set of features in the application:

The table below should help answer questions as to why a particular crate is an Abscissa dependency and whether or not it is optional. Abscissa uses [cargo features] to allow parts of it you aren't using to be easily disabled, so you only compile the parts you need.
- §
winapiis a facade for either winapi-i686-pc-windows-gnu or winapi-x86_64-pc-windows-gnu which aren't explicitly listed for brevity and are only required on Windows platforms.
